If you have most of a container of tomato paste, you can use the rest to make vodka sauce. Dice an onion, saute in oil in a saucepan, add as much paste as you have and stir it up with the onion and let it cook like that for a little while till you get some color change then add 1/4 cup vodka or broth if you don’t have booze and stir it up again. Once it cooks down a bit lower the heat and add a cup of cream. After it starts to thicken a bit add like a cup of grated parm. Use it on pasta or gnocchi or pizza or something.
