Place a large skillet over medium-high heat and cook onions and peppers in olive oil until tender (about 3-5 minutes). Add garlic and butter and cook until fragrant and butter is melted.
Add water, ZATARAIN'S® Spanish Rice and 1/2 cup of salsa. Stir well and bring to a boil.
Reduce heat to low, cover, and simmer, stirring occasionally, for 20 minutes or until rice is tender.
Evenly spread shredded chicken over the top of the rice mixture. Top evenly with remaining 1 cup salsa and cover with cheddar cheese.
