1 3/4 to 2 1/4 cups all-purpose flour 1 envelope pizza crust yeast 1 1/2 teaspoons sugar 3/4 teaspoon salt 2/3 cup very warm water
(120 to 130 degrees) 1 tablespoon oil 1 box (12 ounces) shell pasta and cheese sauce mix 1 cup (4 ounces) shredded mozzarella cheese 1 cup (4 ounces) shredded
American cheddar cheese blend
Put water on to boil for macaroni and cheese (refer to package directions). Preheat oven to 425 degrees.
Combine 1 cup flour, undissolved yeast, sugar and salt in a large bowl. Add very warm water and oil; mix until well blended, about 1 minute.
Gradually add enough remaining flour to make a soft dough. Dough should form a ball and will be slightly sticky.
Knead on a floured surface, adding additional flour if necessary, until smooth and elastic, about 4 minutes. Cover while preparing macaroni and cheese according to package directions.
Pat dough with floured hands to fill greased pizza pan or baking sheet or roll dough on a floured counter to 12-inch circle; place in greased pizza pan or baking sheet.
Form a rim by pinching the edge of the dough.
Spread macaroni and cheese over crust. Top with shredded cheeses.
Bake on lowest oven rack for 12 to 15 minutes, until cheese is bubbly and crust is browned.
