reheat oven to 250 degrees. On a baking sheet, lay out pretzels in a single layer and place a Rolo candy on each pretzel. Put these in the oven for about 3-4 minutes, or until the candy is soft but not melted. Chop the apple in small chunks. Squeeze a little lemon juice on them if you would like to help keep from turning brown. Place one apple on the end of a toothpick and push into one of the Rolo Pretzels. Repeat until all the Rolo pretzels have apples. Ready to serve!
