Preheat the oven to 400 degrees. Add the grape tomatoes, minced garlic, olive oil, sea salt and fresh cracked pepper, to taste, in a baking dish. Toss to coat evenly.
Roast in the oven for 10 minutes, stirring them occasionally, until plump and ready to about to burst. Remove from the oven.
While the tomatoes are roasting, prepare the orzo in boiling water, per instructions. Drain the orzo then pour the pasta directly into the baking dish. Add the fresh parsley then season with sea salt and freshly cracked pepper, to taste. Toss to coat the orzo evenly with the tomatoes, their juices, and the minced garlic. Taste and re-season if needed. Pour into a serving bowl and sprinkle with Parmesan cheese. Serve immediately. Enjoy.
