Preparing your own food can be much cheaper than buying premade or frozen foods. Last night's meal was $10 for three people plus leftovers. I could have made it less expensive, but meat is outrageous right now.

I made broccoli beef over white rice. It took 1.5 small onions, some leek, beef that came from the store pre marinaded ($5) and broccoli. I added soy sauce and some random alcohol to caramelize the onions, and salt.
