Preheat oven to 400°F (200°C).

Slice French bread into approximately 1-inch thick slices.

Melt butter in a small saucepan or microwave.

Crush garlic clove and add it to the melted butter. Stir to infuse the butter with garlic flavor.

Brush the garlic butter mixture onto both sides of the bread slices.

In a separate bowl, combine shredded Cheddar cheese, chopped green chiles, and mayonnaise.

Spread the cheese mixture evenly onto the buttered bread slices.

Place the bread slices on a baking sheet.

Bake in the preheated oven until the cheese is melted, bubbly, and lightly golden brown (approximately 10-15 minutes).

Remove from oven and serve immediately.

Enjoy as a delicious appetizer.
