Boil the orzo according to package directions (mine took 9 minutes), drain, rinse with cold water, and set aside.
Preheat your griddle to medium. Add cooking oil of choice, red and yellow peppers, kosher salt, pepper, and Italian seasoning. Cook 2 minutes, mixing with spatulas.
Add Italian sausage to empty space on griddle. Cook both sausage and peppers for 5 minutes, breaking apart the sausage, and continue mixing peppers.
Combine sausage and peppers on the griddle, then add the cooked orzo and garlic. Mix everything together on the griddle for 2 minutes. Add marinara sauce, kosher salt, pepper, and Italian seasoning and cook another 2 minutes, mixing together.
Serve topped with parmesan cheese and fresh chopped basil.
