Which do you buy and how much?

The end of the month has come and you only have $12 left. Your family wants your special Cheesy Chili, they have been known to eat it 5 nights in a row they love it so much. Basically, you mix one part cheese, one part tomato with four parts meat. Sometimes to make it special you add a pinch or two of saffron or serve it with corn chips. A search of the cabinets reveals the basic spices but nothing else you need. You leave the house with this shopping list: meat, cheese, tomatoes, saffron, corn chips and lottery tickets.
