Salsa Chicken Fiesta

When I saw this recipe in one of my new cookbooks I thought it looked delicious and super easy so I had to try it. It was super easy but it wasn't as delicious as I thought it was going to be :( It wasn't bad though, I just need to figure out a way for the crust to not be as dry and a way to give more flavour to the chicken part.
1 1/3 c. bisquick mix
1/4 c. water
2 eggs
2 1/2 c shredded cheddar cheese
6 large boneless chicken breasts, cut into 1/2-inch pieces
1 jar (16 oz.) thick & chunky salsa

Preheat oven to 400F. Spray 9x13 baking dish with cooking spray. In a med. bowl stir bisquick mix, water and eggs. Spread mixture into pan and then sprinkle with 2 c. of cheese. In a skillet cook chicken over med-high heat until no longer pink. Drain juices and add salsa. Heat until hot. Spoon chicken mixture over bisquick mixture within 1/2-inch of edges. Bake for 25-30 minutes or until edges are dark golden brown. Sprinkle with remaining cheese and bake for another 2 minutes or until cheese is melted. This can be served with sour cream and ground red pepper if you like.
