How Many Calories Are in a Large Pizza Slice?

Mellow Mushroom Nutrition Calculator: The Short Answer

The Full Breakdown: What Is in the Cheese Pizza Slice?

The full profile of the Cheese Pizza Slice (Medium) at Mellow Mushroom: 310 calories, 15g of protein, 43g of carbohydrates, 9g of fat, 2g of fibre, 5g of sugar and 700mg of sodium. Against a 2,000-calorie reference day, that is 16% of the day's calories, 30% of the sodium guideline and 10% of the 50g sugar daily value — which is why the same item can be a light choice in one day and the whole budget in another.

Where those calories sit matters as much as the total. Protein contributes 60 of them, carbohydrate 172 and fat 81 — so the Cheese Pizza Slice is a carb-led item, which is why pairing it with a lean protein usually balances the meal. That split, not the headline number alone, is what decides how long the meal keeps you full.

How Does It Compare With the Rest of the Mellow Mushroom Menu?

One number means little without the menu around it. The table below lines the Cheese Pizza Slice up against the lightest item at Mellow Mushroom, the highest-protein item, the best protein-per-calorie pick and the heaviest item on the menu.

For context, the Mellow Mushroom Nutrition Calculator tracks 16 items, and the average one runs about 381 calories. 5 of them come in under 300 calories and 13 under 500, while the heaviest — the Bruschetta — reaches 700. Where a single item sits inside that spread matters more than the item's reputation: menus, not names, decide what a meal costs.

What Pushes the Number Up (and How to Pull It Down)?

At Mellow Mushroom, the headline item is rarely the whole story: size upgrades, sauces, cheese and the side you add by habit regularly contribute as much as the main itself. The menu's own extremes prove the point — the same kitchen produces the Caesar Salad (regular) at 190 calories and the Bruschetta at 700. The gap between a light visit and a heavy one is almost never the restaurant; it is two or three quiet additions.

The reliable defence is to decide the extras on purpose. Keep one rich addition — a sauce, a cheese, a dessert — rather than stacking them, and let high-volume, low-calorie items do the filling: the Spinach & Artichoke Dip leads this menu for fibre at 6g, and fibre is what makes a lighter order still feel like a meal three hours later.

• Lightest item on the menu: Caesar Salad (regular) — 190 calories
• Heaviest item on the menu: Bruschetta — 700 calories
• Best protein per calorie: Meatball Hoagie (half) — 6.8g per 100 calories
• Items under 300 calories here: 5 of 16

What About the Sodium and Sugar?

Calories get the attention, but at Mellow Mushroom the quieter numbers deserve a look. The saltiest item on the menu, the Greek Salad (regular), carries 1710mg of sodium — 74% of the full day's 2,300mg guideline in a single item — while the least salty, the Soft Drink (regular), carries just 40mg. Salt rarely tracks calories: plenty of light-looking orders are sodium-heavy, and plenty of hearty ones are moderate.

Sugar is more concentrated. The Soft Drink (regular) holds 55g — more than the American Heart Association's full-day suggested limit for women (25g) and men (36g) — while most savoury items sit in single digits. The practical rule: check the drink and dessert line first, because that is where the sugar in a Mellow Mushroom order almost always lives.

How Does This Fit the Rest of Your Day?

No Mellow Mushroom order happens in isolation, so place this one against a reference day of about 2,000 calories, 2,300mg of sodium and a 50g sugar daily value. The average item in the Mellow Mushroom Nutrition Calculator runs about 381 calories, which means a typical one-item-plus-side order lands near a third of the day's energy before a drink is counted. That is not a problem to solve — it is a budget to be aware of, and the awareness is most of the value: the rest of the day can run lighter precisely because lunch was counted.

The pattern that works for most people is asymmetry. On a day when Mellow Mushroom is the main event, let the other meals be simple and protein-led, drink water by default, and treat the Soft Drink (regular) (55g of sugar) as the dessert decision made in advance rather than at the till. On a day when the other meals are the occasion, Mellow Mushroom can be the light one instead — the Caesar Salad (regular) at 190 calories proves the menu supports it. Either way, the plan is made once, calmly, instead of being renegotiated at every meal.

• Menu average: ~381 calories per item across 16 tracked items
• Lightest anchor: Caesar Salad (regular) — 190 calories
• Best protein per calorie: Meatball Hoagie (half) — 6.8g per 100 cal
• Fibre leader: Spinach & Artichoke Dip — 6g, against a 28g daily target
• Salt ceiling to watch: Greek Salad (regular) — 1710mg in one item

The Bottom Line

The Cheese Pizza Slice (Medium) at Mellow Mushroom has 310 calories, with 15g of protein, 9g of fat and 700mg of sodium. If your build differs from the standard one — an extra sauce, a different size, a swapped side — run it through the Mellow Mushroom Nutrition Calculator before you order: thirty seconds there replaces every guess in this article with your exact total.
