Section each apple and then sprinkle with lemon juice to prevent browning. Spread about 1 tsp. of peanut butter on each slice. Stick 4-6 yogurt-covered berries on an angle in the peanut butter, then place a second peanut butter-covered apple slice on top. (You may need to secure with a toothpick or extra peanut butter.)
Cool for 1 hour in the refrigerator before serving.
