Method:

1. To begin making Onion and Cheese Pepper Sandwiches, take a medium sized bowl, add the grated cheese, finely chopped onions, black pepper powder and oregano.

2. Mix all the ingredients well and keep aside.

3. Take a slice of bread, place enough filling and press it tightly with another slice. Likewise, prepare the other 3 sets of the sandwich.

4. Heat butter in a skillet on medium flame, place a set of sandwich, cook until the bottom turns golden brown. Flip over and cook the other side too.

5. Similarly, grill the other three sets of sandwiches in the skillet with enough butter.
