I made so many changes to this recipe- but it turned out fantastic! I halfed this & didn't use any bacon. Instead of ricotta I used cottage cheese, I used cheddar instead of feta, & italian bread instead of sourdough. I didn't have red onion, so I used a white one and I didn't have tomatoes, so I just used drained canned tomatoes. I did a mix of rosemary, basil and oregano and used garlic powder instead of cayenne. Also, because I halfed the recipe, I just used 3 eggs instead of 2.5. I served this for dinner with a green salad. I'll be making this again several different ways. Thanks for the awesome recipe!
