I'm going to give you a list lol but I think I'll leave another comment because this one is kind of long. I've just went vegan and just seeing how it goes for now (like literally yesterday lol.)
I went to The Vegan Solution, she sells meal plans that are very cheap, like her 28 day one is only 12 dollars and available as a PDF. If you don't want to do that, she has a lot of "what I eat in a day" videos on her youtube account, many of them are really easy meal ideas.

Example of a meal plan:
(this is the example page you see on her page)
Breakfast: Oatmeal with frozen berries, peanut butter and/or sugar free jelly (for no fat I'm sure you could do other options aside from the peanut butter)
She's also a big fan of oatmeal and "nice cream" which is frozen fruit blended with any type of thing like cocoa powder or vanilla. Then you put the nice cream on top of the oatmeal and it's sort of like a healthy sweet treat.
Lunch: Baked Sweet Potato fries and large salad
Dinner: Burrito Bowl with lettuce, brown rice, salsa, beans, avocado etc..
