These zucchini and spinach feta casserole bites take 50 minutes to make, mainly because of baking time. I make these bites for quick-to-cut dinner parties and snacks featuring blackened zucchini on top of baked eggs and feta.

I stack slices of zucchini in the casserole dish after lightly cooking the zucchini in a pan. Space the zucchini slices so that the egg mixture can cook and bake up between them. The top layer of zucchini stays in place while the egg mixture bakes, creating a layered look. Dark green spinach is visible between the zucchini slices in the casserole dish, enhancing the dish's appearance with the zucchini. The dish is most appropriate for weeknight meals.
Buy a large block of feta and chop it into 1/2-inch cubes to use as a topping. I don't like to shred feta for this dish because I enjoy the browned bits. I use room-temperature eggs and cream and add the egg mixture to the casserole dish, where it turns a light yellow color.
For a main meal, I served this baked dish with Mediterranean rice and beans. I served gluten-free toasted focaccia bread with the custard in this recipe and didn't need to serve other side dishes with this dish for lunch. I garnished the dish with fresh dill immediately before serving, after the feta cheese had browned and the baked dish had been cut into squares.
