How to Make It
Turn Instant Pot to SAUTÉ function. Add onion and oil; cook, stirring occasionally, until onions start to soften, 4 to 5 minutes. Add garlic, thyme, and oregano; cook, stirring often, until fragrant, about 1 minute. Add drained tomatoes, and cook, stirring until tomatoes begin to break apart. Add eggplant, zucchini, and bell pepper, and stir to combine.
Turn Instant Pot to MANUAL function and press HIGH PRESSURE. Cover, turn dial to SEAL, and cook 5 minutes.
Using a towel, vent seal. Once all pressure has released, open, and stir in basil, parsley, capers, and vinegar. Store in an airtight container in refrigerator up to 1 week, or freeze up to 6 months.
For a single serving, heat 1 cup ratatouille in a small skillet over medium-high, and cook, stirring often, until it begins to simmer. Make 2 small cavities; crack 1 egg into each cavity. Reduce heat to medium-low; cover, and cook until whites are set, about 3minutes. Serve immediately with crusty bread.
