Add-ins: 1 cup of any of the following or a mix of the following: dried cranberries or other fruit, walnuts or any other nuts, trail mix, chocolate/butterscotch chips, etc. - or a 1 cup combination of any of the above for true "kitchen sink" style cookies.
Preheat oven to 350ºF. Use parchment paper to line a cookie sheet.
In a large bowl, beat canola oil with sugars until well incorporated. Beat in egg and vanilla extract.
In another bowl, whisk together flour, oats, baking soda and flaxseed meal.
Mix the dry ingredients into wet ingredients a little at a time, until incorporated but not over-mixed.
Drop by the tablespoons onto the parchment lined cookie sheet. Bake for about 10 minutes, until edges are just starting to turn brown. Bake an extra minute or so for a crispier cookie.
