Portobello mushrooms marinated in olive oil and salt and then grilled and served with all the hamburger fixings. Much better than meat hamburgers.
Any pasta with a tasty sauce, either tomato-based, cream based, or both.
Home-grown tomato sandwiches, mozzarella, tomato and basil salad, tomato, cheddar and bread crumb layered casserole, home-made tomato soup with good fresh bread, or a tomato and basil omelet (I like tomatoes).
Stir-fried vegetables and tofu flavored with garlic, ginger and fermented black beans, or stir-fried noodles with assorted vegetable, either Chinese Lo-Mein or Chow-Fun style, or Thai Pad Thai style.
Any one of a number of vegetarian curries. My favorites tend to involve coconut milk and potatoes and are not necessarily Indian. Thailand has some terrific curries.
And there are a lot more options.
