These Ricotta Stuffed Zucchini Boats are a simple make-ahead vegetarian main dish that is oh-so-cheesy, scrumptious and high in protein and low in carbs.
Using a spoon, scoop out the flesh and seeds from zucchini. (Use it in a stir-fry or freeze to put in a smoothie.)
Place the walnuts and parmesan cheese into a food processor and process until crumbly. (You can substitute panko or breadcrumbs for walnuts, if desired.) Evenly coat each zucchini boat with the walnut topping. Season with salt and pepper and a drizzle of olive oil.
