Preheat oven to 350 degrees.
Spray a 9x13 baking dish with non-stick cooking spray.
Cut biscuits into quarters and place them in a single layer in baking dish - set aside.
Next, brown beef in a large skillet on medium-high heat until thoroughly cooked. Drain excess fat. Add chili seasoning packet, kidney beans and diced tomatoes to cooked beef, stir well and allow to cook an additional 5 minutes.
When ready, pour chili evenly over biscuits. Bake on middle rack of oven for 25 minutes.
I have also done it with pizza sauce and pepperoni and cheese. Hotdogs, chili and cheese. Spaghetti meat...so many different options!
