Cook orzo in large pot of boiling salted water until tender but still firm to bite, stirring occasionally. Drain. Rinse with cold water; drain well. Transfer to large bowl and toss with 1 tablespoon oil.
-This can be prepared without a grill. If you have a convection oven, turn the heat to about 425 and cook just until vegetables start to turn golden. You may cook the shrimp in the oven as well, or saute in a pan on the stove. The flavors are definitely better when the vegetables and shrimp are grilled on a barbecue grill. -Don't overcook the vegetables. They should be barely softened when cooked properly.
