Brush one side of each slice of bread with melted butter and place in oven for 10 minutes.
When bread is slightly brown and toasty, spread quince paste evenly to the outer edges of the bread. Add Lamb Chopper® and return the bread to the oven for another 5-10 minutes until cheese is melted.
Remove bread from the oven, sprinkle with basil and salt and pepper. Serve warm.
