1. 1. Prep Your Veggies: Dice the bell pepper and onion, slice the mushrooms and black olives.

2. 2. Brown the Ground Meat: Place a large skillet over medium-high heat. Add olive oil. Add ground beef and cook until browned, about 5-7 minutes. Drain excess fat.

3. 3. Sauté the Aromatics: Reduce heat to medium. Add onion, bell pepper, and mushrooms. Sauté for 5-7 minutes until softened.

4. 4. Season and Sauce: Stir in oregano, garlic powder, salt, and pepper. Cook for 1 minute. Add marinara sauce, stir, and simmer for 5 minutes.
