I'm not vegetarian or vegan, but occasionally do a diet with my wife that makes us get creative with food. Here's a few things I still eat:

Pad Thai is a good place to start

Oreos are surprisingly vegan

Taco Bell's bean burrito, actually most Mexican food can just replace the meat with refried beans.

Bacon bits are vegan, toss them on some pasta like Cacio e Pepe

Chipotle's chorizo is fake pork sausage, get it in either a bowl or a burrito.

Then the classics:

• tomato soup with grilled cheese
• peanut butter and jelly
• pancakes
• mac & cheese
• All cakes and pies (well excluding chicken pot & Shepard's)
