Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 Whole30 compliant breakfast sausage links and cook for 5-6 minutes, turning occasionally until browned and cooked through. Remove from skillet and slice into 1/2-inch pieces.
  2. Step 2: In the same skillet, add remaining 1 tbsp olive oil and 1 small diced yellow onion. Sauté for 3-4 minutes until translucent.
  3. Step 3: Add 8 oz sliced white mushrooms and cook for 5 minutes, stirring occasionally until mushrooms release moisture and become golden.
  4. Step 4: Stir in 2 minced garlic cloves and cook for 30 seconds until fragrant.
  5. Step 5: Add 5 cups packed baby spinach, 1/2 tsp salt, 1/4 tsp black pepper, and optional 1/4 tsp red pepper flakes. Cook, stirring frequently, until spinach wilts, about 2-3 minutes.
  6. Step 6: Return sliced sausage to the skillet, toss everything together, and heat through for 1-2 minutes.
  7. Step 7: Remove from heat and sprinkle with 2 tbsp chopped fresh parsley before serving.
