Creating a Classic Ratatouille is a straightforward process when you follow these simple steps:

1. Prepare the Vegetables: Wash and chop all the vegetables as indicated in the ingredients list.
2. Sauté Onions and Garlic: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onions and minced garlic. Sauté until the onions become translucent, about 5 minutes.
3. Cook the Eggplant: Add the diced eggplant to the skillet. Cook for an additional 5-7 minutes until soft and slightly browned. Stir occasionally to prevent sticking.
4. Add Bell Pepper: Next, add the diced bell pepper to the mixture. Sauté for another 3-4 minutes until softened.
5. Incorporate Zucchini: Now add the sliced zucchinis. Stir and cook for 4-5 minutes.
6. Add Tomatoes: Mix in the chopped tomatoes or canned diced tomatoes, along with salt, pepper, and basil. Stir well to combine.
7. Simmer: Reduce the heat to low, cover the skillet, and let it simmer for about 30 minutes. Stir occasionally to prevent sticking.
8. Adjust Seasoning: After simmering, taste the ratatouille. Adjust the seasoning with additional salt, pepper, or basil as needed.
9. Cool Slightly: Remove from heat and let it cool for 5-10 minutes before serving.

These simple steps will guide you to create a colorful, aromatic Classic Ratatouille that you’ll be proud to serve!
