In a large mixing bowl combine the oats, Rice Krispies, Chex cereal, flaxseed, cranberries, M&Ms and sunflower seeds. You could always add different nuts or dried fruit as well. Trail mix means you can add what you like!

Heat honey and peanut butter in a microwave safe dish for 30 seconds or until softened. Pour over trail mix and mix thoroughly.

Transfer trail mix into a 9-inch x 13-inch baking dish. Pack down firmly.

Refrigerate the trail mix bars for 1 hour before cutting and serving.
