Ingredients

• (Total Time: 20 MIN| Serves: 4)
• 1 medium red bell pepper, chopped
• 1 medium green bell pepper, chopped
• 1 medium yellow bell pepper, chopped
• 1 medium onion, sliced
• 1 small celery stalk, chopped
• 2 garlic cloves, finely chopped
• ½ cup / 120g diced tomatoes
• 1 small chili pepper, finely chopped (optional)
• 2 tbsp / 30ml olive oil
• 1 tbsp / 14g butter
• 2 tsp / 10ml balsamic vinegar
• ½ tsp salt
• ½ tsp ground black pepper
• ¼ tsp ginger powder
• ¼ tsp dried thyme

Instructions

1. Directions
2. Create the Sauce: In a blender or food processor, combine the diced tomatoes, garlic, chili pepper, olive oil, balsamic vinegar, salt, black pepper, ginger powder, and dried thyme. Blend until the mixture is smooth and creamy. Set aside.
3. Sauté the Aromatics: Set your Instant Pot to the ‘Sauté’ function. Once the display reads ‘Hot’, add the butter and allow it to melt completely.
4. Cook the Vegetables: Add the chopped bell peppers and sliced onion to the pot. Stir-fry for 3-4 minutes, until the onions soften and become translucent.
5. Pressure Cook: Stir in the chopped celery, then pour the blended sauce over the vegetables. Secure the lid, set the steam valve to the ‘Sealing’ position, and press the ‘Manual’ or ‘Pressure Cook’ button. Cook on ‘High’ pressure for 3 minutes.
6. Release and Serve: Once the cooking cycle is complete, perform a quick pressure release by carefully moving the valve to the ‘Venting’ position. When the float valve drops, open the pot and give everything a good stir. Transfer to a serving bowl.
7. Garnish and Enjoy: Optionally, top with a sprinkle of grated Parmesan or cheddar cheese. Serve warm and enjoy!
