I found this recipe searching by ingredients because all I had at home were eggs, spinach and feta. I used regular wheat bread, and also a few wheat tortillas that I also had lying around. I didn't have any oregano. I made eight of these for me and my fiance for breakfast. I think saying one cup is a serving is a little misleading. Three or four will fill you up. I really liked how light-tasting these were. I used about five whole eggs, and then two eggs with just the whites, to make the egg mixture a bit fluffier. Overall, these are great because they're light and very easy to make. I'm not judging the flavor too much because I didn't follow the recipe exactly. My boyfriend ended up adding hot sauce to his, probably because of the blandness, which is probably my fault, not the recipe's.
