1/2 cup pumpkin seeds
1/2 cup roasted and salted sunflower seeds
1 tbsp sesame seeds
1 tbsp flax seeds
1 tbsp chia seeds
1/2 cup rolled oats
1/4 cup oil
1/4 cup maple syrup
1/4 cup tahini paste
Combine ingredients. If mixture seems too wet, add oats. If mixture seems too dry, add tahini. Place into a prepared pan, lined with parchment paper. Using a rubber spatula, press down to flatten. Freeze for 2 hours. Remove from freezer and cut into bars. Keep refrigerated.
You can substitute any nut or seed you like or prefer, and, of course, any nut or seed butter in place of tahini.
