There are tons of options! Too many, really!

I'd start with thinking about macros and veggies.

Carbs: rice, bread, other grains, etc.

Protein: beans, tofu, seitan, tempeh

Veggies: all of them they are great.

While these are just ingredients, there are tons of combos that make great food. A nice vegan burrito can just be beans, rice, and veggies (all of the above spiced and seasoned of course) in a nice tortilla. A delicious Indian dal is lentils, spices, and sometimes another base like tomato, and can be eaten with rice and a salad. You can make a nice fried tofu and then eat it in a stir fry and serve with rice. You can treat seitan like as faux meat, more or less, and fry it up in a stir fry or season it and bread it and deep fry it etc etc. You can make a very nice burrito bowl centered on Mexican frijoles negro and dry pan fried corn. Chili is basically just tomatoes, beans, and spices.

There are also several accidentally vegan easy meals, like freezer stuff. There are Chinese veggie dumplings in most Asian markets. I like to get nice frozen potato pierogi. Black bean burgers are great and can be pan fried from frozen. You can spruce up instant noodles with frozen veggies and tofu in a pinch.

There is also a ton of vegan junk food out there and it is A-OK to have some. I just wanted to focus on healthier options first.

Also consider getting both a rice cooker and an I instant pot. You'll eat more rice if you have a rice cooker. Parboiled rice is as nutritious as brown rice but tastes way better IMO. An instant pot enables you to cook dry beans quickly. Dry beans are incredibly cheap and last forever when stored properly. If you want to cook Indian pulses you will need to cook them, I've never seen most of them in canned form.

Also vegans inevitably discover nutritional yeast because it tastes so good and fits a similar savory profile as cheese when combined with garlic powder. It's also very good for you!
