For meal prep, refrigerate slices up to 5 days and reheat in the microwave or oven.

Baked oatmeal is the lazy cook's perfect breakfast, and this version brings a real protein number to the party. Mashed ripe bananas, cottage cheese and eggs whisk into one bowl with rolled oats, then bake until golden with toasted walnuts on top and banana slices that turn jammy in the heat. The cottage cheese disappears into the bake — you would never know it is there — but it pushes every serving to 24 grams of protein at 430 calories, alongside 55 grams of carbs, 14 grams of fat and 8 grams of fiber. It is vegetarian, reheats like a dream, and tastes like dessert you are allowed to eat on a Tuesday. Bake once, slice warm all week with a spoonful of Greek yogurt. If your bananas are spotted and sad on the counter, this is their redemption arc.
