  4. Step 4: In a small bowl, whisk together 3 tbsp extra virgin olive oil, 2 tbsp fresh lemon juice, 1 tsp Dijon mustard, 1 minced garlic clove, 1/4 tsp salt, and 1/8 tsp black pepper until emulsified.
  5. Step 5: In a large salad bowl, toss 4 cups baby spinach leaves with the lemon vinaigrette and toasted walnuts.
  6. Step 6: Slice the rested chicken breasts and serve atop the spinach walnut salad for a satisfying Whole30-friendly meal that reintroduces nuts thoughtfully.

How do I store leftover Sautéed Chicken with Toasted Walnut and Spinach Salad?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Can I substitute ingredients in Sautéed Chicken with Toasted Walnut and Spinach Salad?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Sautéed Chicken with Toasted Walnut and Spinach Salad for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
