Preheat the oven to 400 degrees F.
In a large baking dish, toss the peppers with the olive oil, garlic, and season with salt, pepper, oregano and thyme. Transfer to the oven and roast for 15 minutes, then remove but leave oven on.
While peppers roast, cook the orzo according to packaging. After orzo is drained, combine it with the chickpeas, balsamic vinegar, lemon, olives, sun-dried tomatoes, pine nuts, and season with salt and pepper to taste.
Stuff peppers with mixture, place them back in the baking dish, then fully cover with tomato sauce. Bake for another 15 to 20 minutes, and then serve!
