Heat the olive oil in a skillet over medium heat. Add the garlic and cook, stirring constantly, for 1 minute. Add the orzo and asparagus to the skillet then toss to coat evenly. Add the lemon juice, zest, tomatoes, sea salt and freshly cracked pepper, to taste then gently mix until well combined. Place into a serving dish then top with freshly chopped parsley and Parmesan if desired. Enjoy.
