Preheat the oven to 250 degrees F.
Warm tortillas in oven.
While tortillas are warming, heat a non-stick skillet coated with cooking spray over medium-high heat until hot. Add zucchini, chiles, and green onions and saute for 3 minutes or until tender. Stir in the rice, cheese, salt, and pepper and cook for 1 minute, stirring constantly. Remove from heat and stir in the sour cream.
Fill warmed tortillas with rice mixture. Top with lettuce and tomato. Roll up the burrito and serve with salsa.
