Regular tomato soup (32oz (946ml )) can be used instead of canned condensed soup. The sauce might come out a little too thin. In that case, sift 1 tbsp of all-purpose flower at the end of cooking and stir the stew. When using condensed soup, the sauce might be too thick. Add 1/2 cup water if that happens. Meat can be seared the day before and refrigerated. All the vegetables can be prepared and cooked with the tomato soup the day before.
