I like the "Bear Naked" brand of granola and "Maple Spring" bulk brand. It's best to buy your granola from a natural food section of the grocery store. Most of the ones made by conventional cereal breakfast manufacturers have trans-fats and high fructose corn syrup.
I make it occasionally but don't really use a recipe-kind of a "seat of the pants" concoction. I don't know how much help it will be, but it's something like this:
Preheat oven to 325˚F.
In a large bowl combine some rolled oats (mostly), flax seeds, wheat flakes, rice flakes, sunflower seeds, chopped walnuts or any other kind of grain you might like.
In another bowl, combine some honey and oil-you can also use maple syrup, molasses, rice syrup or malt syrup. Add vanilla, cinnamon or other spices and flavorings that you like. You need about a 2:1 ratio of honey to oil and a ratio of 4 or 5 to 1 of grains to honey mix.
Toss the two mixtures to coat grains evenly then spread evenly on a lightly oiled baking sheet.
Bake about 10-15 minutes, then mix around a little. Bake, tossing in 10 minute intervals until lightly toasted and golden.
Remove from oven and add any dried fruit you like to the hot granola. Cool on the pan, then store in an airtight container.
