This is a delicious restaurant-quality meal, everyone who likes southern cooking will love! A friend of mine gave me this many years ago. She said it was a grand-prize winner at a cook off she went to. It is definitely grand-prize worthy.
Combine flour, seasoned salt, pepper and garlic powder. Add chicken and toss to coat; shake off excess coating.
Heat oil in large skillet over medium-high heat. Add chicken; brown on both sides. Remove chicken from skillet and set aside. Pour off all but 2 tablespoons of oil from skillet.
Add onion, mushrooms, bell pepper, and garlic to skillet; cook until soft. Add sour cream, broth and hot sauce; mix well. At this time, taste sauce and add more of the seasonings and tabasco until you reach your desired taste. Return chicken to skillet and smother with sauce. Bring to a simmer, cover, lower heat and simmer for 25-35 minutes, until chicken is cooked through.
