Mac and cheese is an incredibly simple dish. The name pretty much sums up the recipe. Elbow macaroni, or some other tube-shaped pasta, layered with cheese and cooked with milk or cream. That's all there is. But the simplicity of the dish is only part of its charm. Macaroni and cheese lovers add all sorts of secret ingredients and guard their recipes like new money.
Salt and Pepper to taste
Cook the macaroni according to package directions. Cook about 1 minute less than the package directions. While the macaroni is cooking, cut 16 oz block of cheese into small cubes. Slice Velveeta into pieces. Then, take the cooked macaroni, drain but do not rinse. Return the macaroni to pot. Add butter, milk, cheese cube and slices to hot macaroni. Mix well, until butter and Velveeta melt. The mixture will be soupy. The cheese cubes will not melt completely. Add peppers. Add salt and pepper to taste. Pour into baking dish.
Cover the top with the remaining cheese (grated, sliced or cut into cubes.)
Bake at 350 degrees F. for 35 minutes. You want the top to brown and the pasta to set.
