Roast the eggplants and peppers until the skins are charred and blistered and the vegetables are completely softened.
Place the roasted peppers in a covered bowl for 15–20 minutes to steam.
Peel the peppers and remove the seeds.
Peel the eggplants and allow them to drain for several minutes to remove excess moisture.
Finely chop the roasted vegetables by hand or pulse briefly in a food processor.
Transfer to a large bowl.
Add the chopped tomato, garlic, olive oil, vinegar, parsley, salt, and black pepper.
Mix thoroughly until combined.
Taste and adjust seasoning as needed.
Cover and refrigerate for at least 1 hour before serving.
Serve chilled or at room temperature with warm bread, pita, crackers, grilled meats, or Bulgarian sirene cheese.
