1. Prepare Your Vegetables: Dice your onion and bell pepper into small, uniform pieces. Chop your fresh spinach.

2. Heat the Skillet: Place a medium-sized non-stick skillet over medium heat. Add the olive oil and let it shimmer.

3. Saute Aromatics: Add the diced onion and bell pepper to the hot skillet. Cook for 3-5 minutes, stirring occasionally, until they begin to soften and become fragrant.

4. Cook the Protein: Add the crumbled lean ground turkey or chicken sausage to the skillet with the vegetables. Break it apart with a spoon and cook for 5-7 minutes, until it’s fully browned and cooked through. Drain any excess grease if necessary.

5. Whisk the Eggs: While the protein is cooking, whisk the eggs, milk, salt, and pepper together in a small bowl until well combined and slightly frothy.

6. Add Eggs and Spinach: Pour the egg mixture over the cooked protein and vegetables in the skillet. Immediately add the chopped spinach. Stir gently to distribute the ingredients evenly.

7. Scramble and Melt Cheese: As the eggs begin to set, gently push them from the edges to the center of the skillet, scrambling them until they are mostly cooked but still slightly moist. Sprinkle the shredded cheddar cheese over the top.

8. Finish Cooking: Cover the skillet for 1-2 minutes, or until the cheese is melted and the eggs are fully set to your liking. Remove from heat and serve immediately.
