After having a baby, a neighbor of ours volunteered to bring over food. This is what she brought and since then I've fallen in love with this salad.
4 cups spinach
2 cup strawberries, quartered
raspberry vinaigrette dressing
1/2 cup red onion, chopped
1/4 cup chopped walnuts or pecans
1/4 cup crumbled feta cheese
Combine spinach, strawberries, feta cheese, and red onion in a large bowl. Top with the nuts and serve with dressing on the side.
