Preheat grill or broiler. Season chicken to taste with salt and pepper, and lightly brush with olive oil. Grill or broil, skinside down first, about 10 minutes per side.

Melt butter in a medium skillet over moderate heat. Cook onions with salt and pepper until soft and clear. Add garlic and paprika, and cook an additional minute, stirring constantly. Add remaining ingredients, bring to a boil, reduce to a simmer, and cook, uncovered, about 5 minutes.

Place chicken over individual beds of bulgur wheat, rice or pasta. Ladle on sauce and serve.
