Heat olive oil in a skillet over medium heat. Add onions and bell peppers, cooking until softened. Stir in rice, water, garlic, salt and pepper, bringing to a boil. Cover and cook for 15 minutes until rice is tender.
Mix softened butter with granulated garlic, smoked paprika and kosher salt. Loosen the skin of each chicken and rub the butter mixture underneath and over the skin.
Stuff each chicken with the cooked rice. Tie the legs together with butcher’s twine.
Sprinkle more Out Grilling Sweet BBQ Rub over the outside of the chickens.
Prepare a grill fire to 250° using hickory or pecan for smoke flavor.
Place chickens onto the grill over indirect fire. Cook with the grill closed for 1 hour 15 minutes to 1 hour 30 minutes or until internal temperature of the chickens reach 165° using a digital meat thermometer.
Remove from grill, resting 10 minutes.
Cut chickens in half using poultry shears and serve on a platter.
Garnish with fresh thyme.
