To make that you just blend a can of crushed tomato, 3 cloves garlic, one medium onion and salt/pepper/and Cayenne pepper. Heat over the stove and freeze any you don't plan on using within a week. I plan to use the extra that I made in a stew in the upcoming weeks.
These are kind of addictive - possibly because they are all teeny and bite sized and crispity crunchity.
