I have 2 frozen gallon bags of peeled cored romas. What can I do with them? I wanted to maybe crockpot something because I start my new job Wednesday and wont want to cook. Can i cook them down into sauce, then use my stick blender to puree and add ground beef ( cooked?) and spices and let that simmer for the day? Can i just use 1 bag? Do i thaw them first? HELP!
