Preheat oven to 350 degrees F. Spray a 8 inch square baking dish with non-stick cooking spray; set aside. If you don't have cooked rice, start your rice now.

Using a large skillet, heat olive oil over medium-high heat. Add chicken, Ms Dash seasoning, garlic salt and sauté until done, about 10 minutes. Place chicken in a large bowl or casserole dish.

Using the same skillet, add more olive oil if needed and let warm to medium-high heat. Add onion and cook 4 minutes, until translucent. Add broccoli and cook for an additional minute. Add in spinach and corn, cooking 30 seconds to 1 minute, until spinach is wilted and corn is heated. Transfer vegetable to the same bowl with the chicken. Stir to combine.

Melt butter over medium-high heat in a medium saucepan. Whisk in flour and salt. Cook 1 to 2 minutes or until the flour turns to a light brown.

Slowly whisk in the half and half, only 1/4 cup at a time until smooth and no lumps remain. Bring to a boil, making sure to stir constantly. Cook and stir one minute while lightly boiling. Remove from heat, cool 3 minutes.

Bake in preheated oven for 15 minutes. Add toppings and bake additional 5 minutes, or until cheese is melted and bubbly.

Serve immediately, sprinkle with hot sauce and enjoy!
