  1. Step 1: Preheat oven to 350°F and grease a 12-cup muffin tin with 1 tbsp coconut oil.
  2. Step 2: In a skillet over medium heat, sauté 1/4 cup finely chopped onion, 1/2 cup diced red bell pepper, and 1/2 cup diced yellow bell pepper for 4-5 minutes until softened. Add 1 cup chopped spinach in the last minute until wilted, then remove from heat.
  3. Step 3: In a large bowl, whisk 8 large eggs with 1/2 tsp sea salt and 1/4 tsp black pepper until combined.
  4. Step 4: Divide the sautéed vegetables evenly among the muffin cups, then pour the egg mixture over, filling each about 3/4 full.
  5. Step 5: Bake for 18-20 minutes until the egg muffins are set and lightly golden on top.
  6. Step 6: Remove from oven and sprinkle 2 tbsp fresh chopped parsley over the muffins for a fresh finish. Let cool slightly before removing from the tin.
