Echoes of Greek moussaka are correctly heard here, both in the name and the feel of the dish. It’s a vegetarian take on the hearty, humble, healthful, and completely delicious sheet-pan dish. It works well either as a veggie main or as a side with all sorts of things—piled into a baked potato, for example, or served alongside some grilled meat, fish, or tofu. It’s just the sort of dish you want to have in the fridge ready to greet you after a day at work. It’s also lovely at room temperature, so it’s great for an on-the-go lunch.
Getting ahead: You can make and bake this in advance; it keeps in the fridge for up to three days, ready to be warmed through when needed.
