One of the best side effects of having gone vegan is that the cost of food has gone through the floor. Plant-based staples are dirt cheap and extremely shelf-stable, and because most times it's easier and more interesting to cook for myself, I learned a lot of insanely cheap, yummy, and healthy foods to cook. I just bought 8 lb of Desi chickpeas and 20 lbs of basmati rice โ enough to feed the fucking Artesh for a year โ for about $30 (and I wasn't trying to penny-pinch). The spices, herbs, sauces, oil, nuts, etc. that go into making that, meanwhile, barely even factor in cost-wise.
Even with a non-plant-based diet, you'll find cooking staples like chicken at home saves you a fuckload of money.
