I made "zucchini boats" (sort-of a low carb substitute for baked stuffed pasta) for dinner and they were fabulous!!! I saw recipes for how to do this and here is my version... I didn't really measure.
3 medium zucchini
1 tub part skim ricotta cheese
3 cloves garlic, grated
Salt, pepper, Italian seasoning
Preheat oven to 400. Cut each zucchini in half. Use a spoon to scoop out the zucchini "guts" and form a boat. (Most recipes say to reserve the middles and use them to re-stuff the zucchini but I didn't and I threw the guts away. Yes, it's wasteful but I don't like zucchini seeds. I do the same thing with cucumbers. Ick.) Drizzle zucchini with olive oil and sprinkle with salt and pepper. Place in oven for 10 minutes.
Meanwhile, mix together the ricotta, egg, garlic, salt, pepper, Italian seasoning. Remove zucchini from oven and turn heat down to 325. Stuff zucchini with ricotta mixture and spoon marinara sauce over each piece. Place in oven and bake for 45 minutes. Sprinkle with mozzarella and broil until bubbly.
