1Bring a large pot of salted water to a boil. Add the whole wheat spaghetti and cook according to package instructions until al dente. Drain and set aside.
While the pasta is cooking, heat the olive oil in a large skillet over medium heat.
Add the minced garlic and crushed red pepper flakes to the skillet. Sauté for about 1 minute, until fragrant but not browned.
Add the shrimp to the skillet. Season with salt and black pepper. Cook for 2-3 minutes on each side, until the shrimp are pink and opaque.
Add the lemon juice and zest to the skillet, stirring to combine and deglaze the pan.
Add the cooked spaghetti to the skillet and toss everything together until the pasta is well coated with the sauce.
Remove from heat and stir in the chopped fresh parsley.
Serve immediately, garnished with extra parsley and lemon wedges if desired.
