Bring a large pot of salted water to a boil. Add orzo pasta and cook into according to directions on the package, or until al dente. Drain and set aside.
Working quickly, return the pot to the stove and add the vegetable stock and wine. Stir in the paprika, oregano, thyme, salt, pepper and garlic.
Bring mixture to a boil, then add peas and green onions.
Bring mixture to a boil again, then add shrimp. Cook for 2-3 minutes, stirring often, until shrimp cook all the way through and turn pink.
Return the orzo to the pan along with the lemon juice, lemon zest and butter. Cook for a few minutes until orzo soaks up the sauce.
Serve immediately with parmesan cheese, if desired.
