Prepare all the ingredients. Slice the sausages and cheese. Sauté the sausages briefly. Then, take one slice of bread, spread ketchup and chili sauce, and add the sliced sausages and cheese evenly. Cover with another slice of bread with nothing on it. Repeat this step until all ingredients are used.

Prepare a non-stick pan and heat the butter. Place the bread filled with sausage and cheese in the pan. Then, cover with another slice of bread with nothing on it. Flip until all sides of the bread are golden brown. Once done, transfer to a plate. Repeat the process for the next sandwich.
