There are several options...
Take a ham steak and cut into small cubes or use pieces of leftover ham.
Cook either whole wheat macaroni or several potatoes, diced.
When macaroni or potatoes are cooked, drain and add ham pieces.
I like to use about 1/2 cup Wildtree Kids Cheese and milk or you can make a quick sauce with 2 Tablespoons butter, melt in separate pan. Add 2 Tablespoons flour. Stir well. Add a cup or more of milk and stir until thickened. Add a cup of grated cheese.
Stir this sauce over the macaroni or potatoes and ham and add a side vegetable and voila, dinner is served. Kids love this.
