Keep It Simple, Stoopid. KISS principle states that most systems work best if they are kept simple rather than made complicated; therefore, simplicity should be a key goal in design, and unnecessary complexity should be avoided. The KISS rule was our inspiration for our newest and simplest granola. Just five ingredients; rolled oats, maple syrup, coconut oil, vanilla and sea salt. Its organic, vegan, nut free, and gluten free.
