Heat oven to 400*F. Pile the peppers and onion on a baking sheet. Pour oil over top and sprinkle with thyme, cumin, and coriander. Use your hands to mix everything together. Spread out into an even layer and roast 30 minutes.

Line a second baking sheet with parchment. Unroll the pastry onto the sheet and cut into six squares. Use a fork to poke indentations all over the pastry, leaving a 1/4 inch border around the edges. Refrigerate until ready to bake.

Increase the oven temperature to 425*F. Brush pastry with the beaten egg. Spread the center of each pastry square with 1 tablespoon of sour cream. Mix half of the parsley and cilantro into the roast vegetables then arrange onto the center of each pastry square, leaving a shallow crater in the center. Bake 10 minutes. Crack an egg into a small dish; carefully pour it onto one of the pastries, letting it settle into the crater that you left. Repeat with remaining eggs. Return to the oven and bake 10-15 minutes, or until the eggs are cooked to your liking.

Top with remaining herbs and season with salt and pepper. Serve immediately.
