In a large skillet over medium-high heat, brown the ground beef and chop it with a spatula.
Cook the beef until it is thoroughly browned and no longer pink. Drain the fat from the beef.
In a large Dutch oven or the ceramic liner of your slow cooker, add the vegetables, corn, beans, and tomatoes. Don’t worry about draining the veggies. This recipe uses the juices of every vegetable to create a delicious savory broth.
Stir in the onion powder, tomato sauce, and beef broth.
Stir in the chopped, cooked ground beef, stirring to combine. Add the tomato sauce.
Heat the stew over medium-high heat until it comes to a boil.
Reduce heat to simmer. Allow the stew to simmer for about fifteen to twenty minutes.
Stir in the prepared Spanish rice. Serve the stew in large bowls.
If you choose to prepare the stew in the slow cooker, add all the ingredients (except for the Spanish rice mix) and cook the stew on low for 6 to 8 hours or on high for 2 to 4 hours.
Before serving, stir in the cooked Spanish rice mix.
To store the leftovers, allow the stew to cool to room temperature.
Place the stew in a container with a tightly fitting lid and store it in the refrigerator for three to five days.
To reheat the stew, put a serving in a microwave-safe bowl and microwave it for one and a half minutes. Stir to make sure it is completely warmed. Alternately, you can reheat the stew in a saucepan until it is steaming.
