Preheat oven to 350 degrees. Place all ingredients, except sunflower seeds (optional) into blender. Puree until smooth. If using sunflower seeds, add to blender and hand-stir. Scoop out the entire mix and pour into greased loaf pan. Spread evenly with butter knife/spatula.
Bake for roughly 35 minutes. Bread should be crispy and browned on top. Let cool. Slice and serve with your favorite nut butter, cheese, pesto, olive spread, or hummus.
