In a small bowl combine garlic, olive oil and salt. Set aside.
Slice baguette into 1/2-inch (1.5 cm) thick slices. Brush baguette slices with garlic oil and place on cookie sheet. Toast in broiler about 1-2 minutes on each side until golden brown. Remove from broiler. Bread should be crisp on the outside, but still soft in the centre. On each slice of bread place about 1 tbsp (15 mL) chicken breast and 3 grape halves, then top with 2 tbsp (25 mL) grated cheese.
Place cookie sheet about 8 inches away from broiler and broil for 2-3 minutes until cheese is melted and bubbly. Place on serving platter and sprinkle with snipped chives and pepper. Makes 24 pieces.
