Make ends meet. Look for leftover cheese ends (or ask at the deli counter). Most grocery stores sell them at a discount. Use the pieces to make a delicious sauce for broccoli or to liven up your favorite mac and cheese recipe.
Skip buttermilk. Don’t buy buttermilk if you need only 1 cup. Instead, mix 1 cup milk with 1 tablespoon lemon juice, shake, and you’re all set!
