Heat oven to 350 degrees F.
Place nuts and seeds on a lined baking tray. Toast in oven for 5-15 minutes until golden brown. Since oven times and temperatures vary check them frequently as the nuts and seeds will burn quickly.
Place all ingredients in a high speed blender with toasted nuts and seeds. I like to start with 1 tsp of tahini and add more if needed.
Blend until smooth, using the blender tamper attachment to push down the mixture into the blades.
Blending may take 5-10 minutes depending on the speed and power of your blender.
Taste and add salt or additional sweetener if desired.
