Place spring mix, spinach, red onions, strawberries, and feta cheese in a large bowl.
In a separate bowl, mix together olive oil, the juice of one lemon, salt, and pepper.
Pour the dressing over the salad and toss to coat.
Notes
This salad is especially good during strawberry season when the berries are naturally sweeter.Keeping the dressing separate helps the spinach stay fresh longer.Baby spinach works best because it’s tender and easier to eat raw than larger mature spinach leaves.
