If you are using ground meat, please brown it first and build the soup from there. If you are using leftover roast you can add it at the end or at any point you desire. The sooner you add the meat the more tender it will be.
sauté the onion, garlic and peppers for 3 minutes.
add in the tomatoes, broth, carrots, spices and herbs and the soup mix.
bring to a boil and cook until soup mix is tender. Usually 45 minutes.Add meat when desired.
taste and see how much salt and pepper you wish to add.
serve and enjoy
Notes
I use great value (Walmart) soup mix. It is a blend of rice, barley, lentils and yellow/green split peas. If you cannot find this or something similar you can use an equal amount of any of the ingredients that make up soup mix ie: ¾ of a cup lentils. Or ¾ of a cup rice. note that some of these absorb more water than others and it may be necessary to thin out your soup if using just rice or barley.
