What can I substitute for tomato paste to thicken a marinade? This recipe calls for 2 TB tomato paste in the marinade. I assume it is to thicken it so more stays on the meat and veggies. I don't want to open an entire can of tomato paste just to use 2 TB. Can I substitute anything else in its place?
In the future buy real Italian tomato paste in the tube. You'll use it all up, it lasts and lasts.
