Step 3
Heat the vegetable oil in a large skillet over medium-high heat. Add the venison cubes, and cook until golden brown on all sides, about 10 minutes. While the venison cubes are browning, whisk together the tomato paste and beef broth in a slow cooker until the tomato paste has dissolved. Stir in the water, brown sugar, Worcestershire sauce, mustard powder, paprika, garlic, onion soup mix, potatoes, carrots, celery, chopped onion, peas, Brussels sprouts, and the browned venison cubes.
