TIP #1: This is a great recipe for presentation, but depending on the vegetables used, may take more or less time than expected. I had large red bell peppers and it takes about 40 minutes for them to get very soft. But... these were large hearty peppers so again, it can vary. Keep an eye on them.
TIP #2: Try adding some basil if using tomatoes or eggplant.
TIP #3: Remove seeds from tomatoes or eggplant because these can create a bitter taste.
