Preheat oven to 375 f. Slice all your vegetables 1/8 in. thick (I used a mandolin). Then in a frying pan over medium heat, saute your onions, bell peppers and garlic until softened. Around 4-5 minutes. Then add crushed tomatoes and simmer over medium low heat for about 20 minutes. Next, in a baking dish or a cast iron skillet, add your sauce and spread evenly over the bottom of the pan. Then layer your sliced vegetables. In a small bowl, mix garlic, basil, thyme oil, and S&P. Mix until combined. Drizzle over your Ratatouille and cover with Tin foil or a lid. Bake for 40 minutes. Then uncover and bake for 20 more minutes. Serve and enjoy!
