Prepare all vegetables ahead of time, peeling, cutting, cubing, whatever is necessary.
In a Stock Pot, on Medium-Low heat, place your chopped onion, garlic, butter
and carrots to sweat. Cover with lid and allow veggies to sweat to soften.
Stir in your tomato sauce and the can with 1/2 C of water in it to use all the tomato sauce that was stuck in the can.
Allow to simmer for a few minutes, just until all has merged with mixture. Now remove this into a large mixing bowl
