Cheesy Beef and Vegetable Frittata

Ingredients

• 6 eggs
• 1 cup milk
• 1 cup grated cheese
• 2 tbsp unsalted butter
• 1 lb beef sirloin, cubed
• 1 medium onion, diced
• 2 cloves garlic, minced
• 2 medium bell peppers, diced
• 2 medium tomatoes, diced
• 1 tsp dried thyme
• Salt and pepper, to taste
• 1 loaf bread, cubed
• 1 cup vegetable sauce
• Fresh parsley, chopped (optional)

Instructions

Step 1: Preheat the oven to 375\u00b0F (190\u00b0C). In a large mixing bowl, whisk together eggs, milk, grated cheese, salt, and pepper. Add the cubed bread and toss to combine. Heat 1 tablespoon of butter in a large cast iron skillet over medium heat. Add the diced onion and cook until translucent, about 5 minutes. Add the minced garlic and cook for 1 minute, until fragrant. Step 2: Add the cubed beef to the skillet and cook until browned, about 5 minutes. Add the diced bell peppers and cook until tender, about 5 minutes. Add the diced tomatoes, thyme, and vegetable sauce. Stir to combine. Step 3: Pour the egg mixture over the beef and vegetable mixture in the skillet. Cook over medium heat until the edges start to set, about 5 minutes. Step 4: Transfer the skillet to the preheated oven and roast for 20-25 minutes, or until the frittata is golden brown and set. Remove from the oven and let cool for 5 minutes. Step 5: Slice the frittata into wedges and serve hot, garnished with chopped parsley if desired.
