To make the Whole Wheat Cinnamon-Sugar Tortilla Chips:
Heat oven to 350 degrees. Spray 2 large baking sheets with non-stick spray.
Mix the cinnamon and sugar in a bowl.
Cut tortillas into 8 triangles using a pizza cutter. Using a brush, lightly brush melted butter onto both sides of the sliced tortillas and then toss the tortillas with the mixture of cinnamon and sugar.
Place in a single layer on baking sheet. Bake for about 5 minutes on each side until desired consistency.
To make the Chocolate Sauce:
Melt the chocolate chips in a glass bowl in the microwave for about 1 minute watching carefully and stirring occasionally.
On a serving dish, place a layer of whole wheat cinnamon-sugar tortilla chips. Sprinkle strawberries and blueberries on top, then add another layer of chips and continue until you have used all berries. Drizzle the melted chocolate on top of the nachos. You can add a dollop of whipped cream to the top.
