Another thing, if you're looking for accessible, and coming from a position of non-vegan cooking for vegan: cooked then drained lentils can slot in pretty well for beef crumbles in a lot of recipes, as long as you take care to not cook them until they become mushy.

For instance, lentils in a shepherd's pie is great, just add a touch of soy sauce to make it more savory.

Or last night I made some taco filling with lentils. I just drained them, and mixed them with some good seasoning. You could easily use premade seasoning, but I blend a can of condensed tomato soup with a can of canned chipotles, some dried peppers (to taste), garlic (to taste), and a whole onion.
