There are so many plant based treats! I highly recommend raiding asain groceries (particularly Chinese and Thai, but also Korean) if you’re not a usual shopper there. So many premade things/affordable substitutes (usually not the healthiest but it’s not like anyone eats animal products because they’re healthy anyway) and wonderful snacks like https://msshiandmrhe.com/latiao/

I personally am a fan of this “omlette” as a quick and easy make once, fry when hangry each week https://www.copymethat.com/r/i55XAfMM2/vegan-egg-moong-dal-omelette/ you can throw whatever in it too.
