1 loaf cocktail rye
1/2 lb. kielbasa, cut about 1/2" rounds
1 jar Kraft horseradish sauce
1 (10 oz.) cracker barrel cheddar, cut in 1/2" squares

Spread each slice mini rye with horseradish sauce. Lay kielbasa rounds on top and cheese squares on top of kielbasa. Do this to fill 1-2 cookie sheets. Bake at 375 degrees until cheese melts. Serve warm.
