I've been vegetarian for 9 years and I'm not a very good cook, either. But I do eat meals that are healthy and tasty, while simple! Here are some of my "staples":
Breakfast burritos (at any time of day):
- Stick a frozen tortilla on the oven rack to warm up, with the oven on the "warm" setting, with sliced cheese melting on top of it (optional)
- While the tortilla is warming, fry an egg, then put it on the tortilla.
- Add some kind of vegetable - e.g. chopped tomatoes, broccoli that you've sauted in the same pan with the egg, raw spinach, or whatever.
- Top with salsa and/or guacamole and/or sour cream
Sweet potato peanut butter soup:
- Chop up about 4 or 5 sweet potatoes (peeling is optional) and a large onion (more or less if you want), and boil in vegetable broth until soft enough to mash with a potato masher. (OR, blend with an immersion blender).
- Add a few big spoonfuls of peanut butter (the kind without sugar), and mash it up some more with the potato masher.
- Cook a little longer, with a cover on the pot if the soup bubbles too much...it always does for me.
- Add salt, pepper, and cayenne pepper to taste
My favorite pasta, although it's weird to other people:
- Cook spaghetti as usual
- Heat a jar of spaghetti sauce, along with some fake meatballs (e.g. the frozen kind), and nutritional yeast
- Pour sauce on spaghetti and top with a can of crushed pineapple, and parmesan cheese
Pizza, the cheating way:
- Use a pre-made crust. Top with a jar of pizza sauce, shredded cheese, and fresh chopped veggies.
Simple things like oatmeal or salad can be a meal, if you add enough stuff to it. I like oatmeal cooked in coconut milk with frozen raspberries and honey added, or oatmeal with walnuts and banana chunks and milk. Salads can include nuts and seeds, or various cheeses, chopped boiled egg, fake bacon bits, croutons, chickpeas, green peas, pomegranate seeds, etc., etc...
My favorite squash:
- Slice a delicata squash into rings about an inch thick, and bake until soft.
- Slightly toast some walnuts, on a baking tray in the oven
- Top each squash ring with a dollop of ricotta cheese, sprinkle with walnuts, then drizzle with honey
I frequently eat a lot of hearty "snacks" that count as meals for me... e.g. cottage cheese with fruit mixed in (pineapple, grapes), apple slices with PB, an avocado with honey mustard dressing (I chop the avocado in half and remove the pit, then fill each little hole with dressing, and eat the avocado with a spoon), carrot sticks with hummus. Sometimes my breakfast is butternut squash soup - the pureed kind that comes in a box - drunk from a mug like it's a smoothie!
You can turn chips and salsa into a meal by mixing the salsa with cottage cheese (or plain yogurt), beans from a can, nutritional yeast, guacamole, etc.
