Prepare all of the vegetables and divide them all in half.
Add one half of the vegetables into an Instant Pot or slow cooker, along with one can of diced tomatoes, one quart of broth and seasoning of your choice.
Add the other half of vegetables into a gallon freezer bag along with the remaining can of tomatoes and seasonings. Mark on the bag to add one quart of broth when ready to cook, press air from the bag and freeze.
Cook for 15 minutes in the Instant Pot or 6 hours in the slow cooker. Test for seasonings when finished and adjust to taste.
This can also be simmered on the stove top, stirring occasionally.
