I got this recipe from Soulemama's blog a few years ago and it's one of our favorites. It's fresh, easy, colorful, and keeps well. The original recipe doesn't have the feta, and it's delicious (and fasting!) without it, but with the feta it's even better.
Orzo Salad with Corn, Tomatoes and Basil
2 TBSP fresh lemon juice
1 TBSP red wine or red wine vinegar
1/2 tsp black pepper
1 TBSP olive oil
1/2 tsp salt
3 cloves garlic, crushed
1 cup uncooked orzo (half of a box)
2 cups chopped tomato
1/4 cup chopped fresh basil
2 cups fresh yellow corn kernels
1/2 cup vertically sliced red onion
1 cup crumbled feta (or more!)
Prepare all dressing ingredients and place in a jar. Cover tightly and shake thoroughly. Prepare orzo according to package directions. Drain and place in a large bowl. Spoon half of the dressing over the orzo; toss to coat. Let cool to room temp. Add the remaining dressing, corn, tomato, onion, feta, and basil to the pasta. Let stand for at least 30 minutes.
