The ones here are made with cubed homemade No-Knead Multi-grain Bread, but cutting up store-bought bread works fine too. Whole grain commercial breads might work best but stale white bread works well too.
Take a couple of slices of bread, cube into little squares, then fry in a hot skillet with 1 to 2 Tablespoons of olive oil (add butter too, if looking for deeper flavored croûtons to use on top of soups).
I just grab whatever seasoning strikes my fancy that day...love the smell of cooking oregano, so I often use that along with some other salt/spice mixture. I sometimes use Mrs. Dash, if not wanting added salt. Some Greek seasoning if I've got some feta cheese to go in the salad. Stir and toss the bread cubes in the oil until the edges get a little crispy. Then serve!
Even though making croûtons is very easy, it's one of those things that I'd probably forget to do if I weren't consciously trying to reduce the packaging waste in this household. Yet another area where being green saves me some green!
Hope something green is goin' on in your world today?!
