Prepare the Brown Rice: Bring water and brown rice to a boil in a saucepan. Reduce heat to medium-low, cover, and simmer until rice is tender and water is absorbed, 45 to 50 minutes.
1 cup Water, 1/2 cup Brown Rice
Make the Filling: Heat a large skillet over medium heat. Add beef, onion, and garlic to hot pan; sauté until meat is evenly browned and onion is softened, about 5 minutes. Set aside. Combine seared beef, cooked rice, 1 can of ketchup, Worcestershire sauce, salt, and pepper in a bowl.
Prepare the Bell Pepper: Remove the tops, seeds, and membranes from green, red, and yellow bell peppers. Place the peppers cut side up on a roasting pan. If necessary, cut off the bottoms of the peppers so they stand upright.
6 Large Bell Pepper
Stuff the Peppers with the Filling
1 tbsp Italian Seasoning
Preheat and Start Cooking: Set the oven to Roast mode at 175°C, preheat ON, and cooking time 26 minutes. Press the "Start Cooking" button to start preheating. Once preheated, insert the roasting pan into Level 2 of the oven.
Remove the Peppers from Oven: Using oven mitts, carefully remove the peppers from the oven.
