2 cups macaroni, uncooked
1 1/2 cups milk
3 tablespoons light cream
2 tablespoons butter
2 tablespoons flour
2 cups Cheddar cheese, shredded
1 cup tomatoes, chopped
3 tablespoons green chiles, diced
1/2 teaspoon cayenne pepper
Salt, to taste

Cook the macaroni according to package directions; drain well.

Meanwhile, warm the milk and cream in a small saucepan over medium heat, or in a glass measuring cup in a microwave oven for about 2 minutes. Do not boil.

In another saucepan, melt the butter and add flour, stirring until a paste forms. Pour the warmed milk into the butter mixture and cook, stirring constantly, until thick and creamy. Add cheese a little at a time, stirring until melted.

Stir in tomatoes, chiles and seasonings. Combine the hot macaroni and the sauce, blending well. Pour into a buttered, 2-quart casserole dish. Bake uncovered at 400 degrees F for 35 to 40 minutes, or until top is nicely browned.
