The first step is getting the peppers ready. Method 1: Place the peppers on a cookie sheet and broil on high for 15-20 minutes turning them every 3-5 minutes. Method 2: Roast the peppers directly on a gas stove burner turning every 2-3 minutes.
Once the peppers are very blistered, place them in a large plastic bag (freezer bag) and let them "steam" for a few minutes. At this point preheat your oven to 350 degrees.
Carefully peel the thin skin layer on the peppers.
Cut the stems off the peppers an de-seed the peppers (don't leave any seeds behind and take extra precaution by using gloves). Cut the peppers into large strips. Set the peppers aside once this step is done.
In a large bowl, whisk 12 eggs.
Add the half & half or water to the bowl and whisk some more.
Season with garlic powder, salt and pepper.
Grease a large casserole dish and throw in egg mixture.
Carefully place the pepper slices in the dish.
