Set your oven to 375°F (190°C) to ensure it's ready for baking.
Combine shredded cheese, finely chopped green chilies, onion, garlic, salt, and pepper in a bowl.
Spread a thin layer of butter on each slice of bread to add flavor and crispness.
Place the buttered bread on a baking sheet and evenly distribute the cheese mixture on top.
Bake the bread in the oven for 10-12 minutes until the cheese is melted and bubbly and the bread edges are crispy.
Ensure the cheese is fully melted and the toast has a golden-brown edge for the best texture.
Remove from the oven and optionally sprinkle with chopped cilantro or herbs for added freshness.
Slice the toast if desired and serve immediately while hot for the best taste and texture.
