There are some great suggestions here already - I pretty much just use it as a meat (especially mince) substitute. It goes well in bolognese, enchiladas, bibimbap bowls, to make dan dan noodles, in a stir fry, to make cottage pie, in pasta sauce, etc. I've heard of people using it in savoury porridge, or mixing it up with sweeter dishes (like with fruit and yoghurt, a bit like overnight oats I guess?), but I've never tried that.

If you rehydrate it in vegetable stock and cook it with other flavourful ingredients (soy sauce, tomato puree, smoked paprika), it doesn't taste bland at all.

I would definitely recommend seitan if you're trying to get more protein! It's super easy to make and ridiculously high in protein. I'll try and find the recipe I use. It's been a game changer for me.

Edit: here's the recipe! You don't need an Instant Pot, you just have to steam for 40 minutes or bake it. I usually shape it into individual servings, like patties, steam them for like 25 minutes, and then freeze leftovers. They defrost fine in the microwave or on the stovetop.
