This savory steak and pepper stir-fry combines tender sirloin steak with vibrant red bell peppers, green bell peppers, and onions. The fresh vegetables, combined with soy sauce, Worcestershire sauce, and a hint of brown sugar, create a balanced, flavorful dish that’s perfect for dinner. The garlic and vinegar add a subtle tanginess, while the beef bouillon enhances the richness of the broth.

To begin, heat olive oil in a skillet over medium heat and brown the sliced sirloin steak until it’s fully seared on all sides. In a separate pot, bring water to a boil, dissolve the beef bouillon, and add the cornstarch mixture. Pour the bouillon into your crockpot, combining it with Worcestershire sauce, soy sauce, and brown sugar for a sweet and savory base. Don’t forget to season with salt and pepper to taste.

Add diced tomatillos to the mixture along with the browned steak and thinly sliced onions. Let everything cook on low heat for 6-7 hours, or 3 hours on high heat, allowing the flavors to meld together and the steak to become melt-in-your-mouth tender. About an hour before finishing, stir in the sliced red and green bell peppers to maintain their crunch and color.

Once done, garnish the dish with thinly sliced green onions and serve over a bed of steamed rice with a side of fresh salad. This hearty, satisfying meal is perfect for any occasion, with its bold flavors and wholesome ingredients bringing comfort and delight to your table.
