Add roasted sunflower seeds to a food processor and blend for 5 to 7 minutes or until butter forms. Scrape down sides as needed. Resist the urge to add any additional oil or water.
Add salt, chia seeds, flax seed, hemp seed, and pumpkin seeds. Pulse to combine.
Taste and adjust flavor as desired, adding more salt, or a bit of sweetener of your choice. Avoid using liquid sweeteners, as these cause the butter to seize up and lose form.
Store in a mason jar in the fridge and spread overprotein bars or toast as often as you like.
