Here's an easy appetizer that is tasty and quick. I found it in Bon Appetit magazine years ago and have been making it ever since.
1 1/2 cups shredded cheddar
1 cup chopped black olives
1/2 cup mayo
1/2 cup sliced green onions
Mix all ingredients together, spread on English muffin halves, quarter and bake at 400F for 10 to 15 minutes.
