Home-recipe meat lasagna. A single restaurant slab is often 350g or more, and the cut size is the main thing people misjudge.

How does lasagna fit your goals?

Lasagna delivers a balanced macro profile (34g protein / 32.8g carbs / 27.3g fat per 1 piece (250g)), which makes it easy to fit into almost any tracking plan. Foods like this are particularly useful as base ingredients in meal prep, because they don't lock you into a specific macro split — you can pair them with whatever your daily target needs more of.

Micronutrients worth noting

Beyond the macros, lasagna pulls real weight on fiber (10% DV), calcium (52% DV), and iron (13% DV) per 1 piece (250g) — the kind of micronutrient density that calorie counts alone don't show. Worth flagging on the other side of the ledger: a serving carries 45% of the daily sodium limit, which matters if you eat it often.
