(Makes 8 servings.) Pound each raw chicken piece with mallet or foil- covered brick. Beat together butter and cheese spread until well blended. Mix in onion, salt, monosodium glutamate and chilies. Divide mixture equally among the 8 flattened chicken pieces, placing a portion towards 1 end of each piece. Roll up each piece, tucking in ends to completely enclose filling. Fasten rolls with toothpicks.
Dip each roll in melted butter to cover, then coat with mixture of cheese crackers and taco seasoning mix. Arrange rolls in 12 x 8 x 2 inch dish. Cover with wax paper. Place dish in microwave oven and cook 10 to 12 minutes.
