I freeze a lot of peppers - they all start to ripen at once and I can't use them fast enough. I wash and core them. Then I slice them in half inch or so strips, throw them in a quart freezer bag and into the freezer. I keep adding to the bag until it's stuffed. Then, I start another one. When thawed, they will not have that crisp pepper texture, but they are fine for chili, spaghetti sauce, casseroles, etc.
