Place 1/2 teaspoon salt in rapidly boiling water. Add 1 cup elbow macaroni. Cook for about 8 minutes, stirring occasionally. While the macaroni is cooking, prepare the other ingredients of your Chili Mac 'N Cheese Skillet. In a medium pot, heat a can of chili with beans over low heat. make your cheese sauce: Melt 1 tablespoon of butter in a skillet. Remove from heat and add 2 tablespoons flour. Stir until combined. Add 3/4 cup milk and 3/4 cup shredded Velveeta cheese. Stir, and then move the skillet of cheese sauce back to the stove and cook, stirring constantly, until smooth and bubbly. Drain your macaroni through a colander into the sink, and return it to its own pot, so you can bring it to the stove and add it to your cooked cheese sauce. Now, add your 2 heated cans of chili. Stir, and your Chili Mac 'N Cheese is done! Serve hot from the skillet, or pour into a casserole dish for serving at the table! Kids *love* this!!!
