- 1 tablespoon vegetable oil, or as needed
- 1/4 cup chopped fresh flat leaf parsley
- 1 slice toasted white bread, torn into small pieces
- 1/2 lemon, juiced

- 1/4 teaspoon dried thyme
- 1/4 cup olive oil
- 1/4 teaspoon kosher salt
- Preheat an outdoor grill for medium-high heat and lightly oil the grate.
- Rub red pepper, yellow pepper, and onion slices with vegetable oil to prevent sticking.
- Grill on the preheated grill until blackened on both sides, about 5 minutes per side.
- Put grilled peppers in a paper bag, seal tightly, let stand for 10 minutes. Remove peppers; discard skins, seeds, and stems. Chop peppers and onion slices roughly.
