"This was just okay for me and the family. I love eggplant but not prepared this way."

"This recipe was super easy and delicious! My whole family enjoyed it. It will be a staple in our home from now on. None of has ever had ratatouille before and I'm so glad I decided to make it. It smells wonderful cooking and cooks up beautifully. I ended up cooking mine on high for a couple hours and then on low until dinner. This is such a lovely and healthy meal. Thank you to Jolene for sharing! :)"

"So excited to try this recipe when I found it. Just was waiting for the summer produce to come on! Unfortunately, after investing in farm fresh produce at a local farm, my husband & I were terribly disappointed. I would have a lot rather used my fresh produce in other yummy summer recipes than emptying them down the disposal. Granted, it smelled delicious while cooking, which took about an extra hour to be done."

"This was so easy to make. I was a little leary about the black olives but they complimented the dish. I used this as a side dish, but with the leftovers I reheated and put over cooked pasta noodles. This is a great dish, very flavourful, colourful and light. I will definitely make this again and again."
