Grease a 9 X 13 dish with butter, and set aside.

In a large roasting pot over medium heat, melt the half stick of butter, and add the bag of marshmallows. Stir until completely melted.

Add the Cheerios to the melted marshmallow mixture and stir to coat the cereal.

Add the freeze-dried strawberries and bananas, and stir well to blend.

Place the cereal mixture in the 9 X 13 dish and spread evenly with a large spoon or spatula.

Place the dish in the refrigerator for about an hour to completely cool and set the bars.

Remove from the refrigerator and cut bars into 2-inch by 3-inch pieces.

Melt the white chocolate in the microwave, dip the bottoms of the bars in the white chocolate, and drizzle a little on the top. Place a strawberry in the chocolate center of each bar.

Place the bars on parchment paper until the white chocolate hardens, about an hour.

Serve and enjoy!
