Heat a large Dutch oven over medium-high heat. Coat pan with cooking spray. Add carrot to pan; sauté 6 minutes. Add onion, basil, thyme, and garlic; sauté 4 minutes. Add tofu, eggplant, and zucchini; sauté 4 minutes or until tender. Add chopped tomato, Pesto Coulis, and tomato sauce; bring to a boil. Reduce heat, and simmer 30 minutes, stirring occasionally. Remove from heat; stir in cumin, salt, and pepper.
I thought the ratatouile itself was tasty and simple to prepare. The pesto coulis was a waste of time and didn't add much to the recipe. I would have added the fresh parsley and basil directly to the recipe and skipped that part. I served it with whole wheat pasta (and used the pesto on the pasta with parmesan cheese).
