Honestly, the precooked rotisserie chickens most places make are typically loss leaders to get you in the store. It's the only affordable way I can buy a chicken,(any other kind of meat is beyond my comprehension of how anyone affords it unless they're rich fucks), that doesn't involve buying like a month's worth of chicken in bulk because as one person I don't need too much. I used to buy a kg of meatballs too, but they've gone up about 30% over the past year so it's just the chicken now if I want meat.

I usually buy a big bag of frozen veggies, lentils, beans, and rice and just make stir fry stuff with the cheapest sauce I can find. If I'm feeling fancy I buy nice noodles and use that instead of rice.
