Lemon Shrimp with Rice Recipe. GP: sub cayenne or another single chile powder for red pepper flakes (World Market & other stores sell a shaker of multiple chile flakes & powders). Instead of lemon wedges, add 1 tsp lemon juice (fresh squeezed & strained) with the shrimp. Once shrimp are cooked, add more lemon to taste. Skip parsley if needed. Healthy & summery.
