How to Make It
Heat broiler. On a broilerproof baking sheet, broil the peppers, turning occasionally, until charred, 8 to 12 minutes. Wrap each pepper in a paper towel; let cool for 10 minutes. Use the paper towels to slide off the skins. Remove the seeds and cut the peppers into strips.
Heat oven to 400° F. Slice ½ inch off the top of each head of garlic and place the garlic on a sheet of foil. Drizzle with 1 tablespoon of the oil and season with 1/8 teaspoon each salt and pepper; wrap tightly. Roast until tender, 45 to 55 minutes. Squeeze the cloves from their skins.
Meanwhile, place the baguette slices on a baking sheet and brush with the remaining 2 tablespoons of oil. Bake until golden brown, 6 to 8 minutes.
In a small bowl, mix the cream cheese and Feta. Top the baguette slices with the cheese mixture, garlic cloves, peppers, and parsley.
