They can be frozen.My kids make panini's,it's their favorite roll.
You can make croutons with it.I cube them into small pieces,dehydrate.Then season and finish them off in the oven.
This is Mcnerd's recipe.It's really good,the seasoning are on the spot.
10 slices bread -- heels are fine (homemade or store bought)
1/2 teaspoon basil
1/4 teaspoon oregano
1/4 teaspoon garlic powder
1/2 teaspoon celery salt (or 1/2 teaspoon salt -- and 1/8 teaspoon celery seed)
1/4 cup oil -- (1/4 to 1/3)
First make 2 piles of your bread. Using a very sharp, serrated knife, slice them into small cubes. I make 5 cuts each direction, one down the center, and two to each side, but you can do it the way that works best for you. Place all of the bread cubes into a large bowl.
Sprinkle on the seasonings. Toss briefly to mix in the seasonings. Next dribble in the oil somewhat evenly. Now gently toss everything together. The oil will help the seasonings stick to the bread and also make the bread crispy without actually having to fry it. Spread the croutons on a large cookie sheet, use two if you need to. Bake them at 350 degrees for about 20 minutes or until they are crisp. Remove from the oven and allow to cool on the pan. Store the croutons in a plastic bag, or resealable container. Serve on salads, or tossed in omelettes, or on top of plain spaghetti and Parmesan cheese.
If your with me that's great. If not. Get out of my way.
