Boil the pasta according to package directions, then place in a large skillet. Add in 1 tbsp olive oil, the Parmesan cheese, green onions, juice from half of the lemon, and 1 minced garlic clove. Salt and pepper to taste, and stir together over low heat until warmed through.

Cook the shrimp in a small pan with the remaining lemon juice and remaining garlic. Add salt and pepper as desired. Continue cooking until the shrimp is lightly browned, with a grilled look. 

Divide the pasta between two plates and top with the shrimp. Garnish with lemon wedges, parsley, and additional Parmesan cheese.
