In a large bowl, add bisquick and 1 cup water. Mix well. Spread into prepared pan. Set aside.
Brown beef in a large skillet until no longer pink. Add taco seasoning and 1/4 cup water and heat for an additional 3-5 minutes. Spread on top of bisquick layer. Add diced tomatoes on top.
One way to tweak this recipe to your tastes is the level of spice involved. For this version, we used green chilies to add a little heat. And, while technically green chilis and jalapenos are the same thing, I think putting from fresh sliced jalapenos into this recipe would be delicious. You could also mix in some taco cheese or pepper jack cheese to add even more kick!
Let’s be honest, this recipe wouldn’t be considered a light and lean dish. So, if you are looking to pump the breaks on the calories, you could certainly make some adjustments there as well. Try subbing the ground beef for ground turkey or chicken. You could also use low fat or light mayonnaise, cheese or sour cream.
