You can complain all you want about how poor you are that you can’t eat beans and lentils, but the entire world outside of US, Canada, and Western Europe is proof of the contrary.
It takes 20 minutes to cook lentils and rice. 30 to cook beans if you have a pressure cooker. These foods are dirt cheap, shelf stable, and sold everywhere. My local gas station sells Goya beans.
I’m sorry about your situation, but cooking and feeding yourself is just part of living whether vegan or not. This widespread idea in the US that being poor means you should be eating expensive unhealthy prepared meals is strange. It will only make your situation worse.
