If you're young and without a job, burritos are definitely in your price range; you just have to be willing to make it yourself. It's not hard to get close to that Mission-style burrito with a little patience and buying in bulk. Get an Instant Pot for the beans. There's a ton of recipes for decent beans on YouTube. Make your own salsa; it's not hard. Grate your own cheese (80g/burrito). Most places bulk up their burritos with rice. Use red/spanish/mexican rice, which is super simple to make. Use a 13.5-inch flour tortilla, which can be found at most restaurant supplies or your local mercado. Pro tip: use roasted veggies instead of rice. You can do it!
