Heat olive oil in a large nonstick skillet over medium-high heat.
Add chopped onion, and saut 5 minutes.
Add celery and bell pepper, and saut 5 minutes. Stir in basil, thyme, and garlic, and saut 2 minutes. Stir in flour, and cook for 1 minute. Gradually stir in water and next 9 ingredients (water through tomatoes), and cook for 1 minute.
Remove from heat, and stir in rice, green onions, and parsley. Spoon shrimp mixture into an 11 x 7-inch baking dish coated with cooking spray.
Unroll both dough portions (do not separate dough into breadsticks); roll dough together, forming a 12 x 10-inch rectangle.
Place dough on top of shrimp mixture, pressing to edge of dish.
Cut 5 slits in top of crust to allow steam to escape. Gently brush 1 tablespoon garlic spread that is packaged with breadsticks over crust; reserve remaining spread for another use.
Bake at 350 for 30 minutes or until golden brown and bubbly around the edges.
