Blend all together in a blender. I add the poppyseeds after blending the rest, just to make sure they stay intact. Add another tablespoon vinegar if you'd like it more vinegar-y. Goes very well with spinach salads, and any green salad with fruit, seeds, or nuts. Store in the fridge in a jar. Should store well for at least a week, but I use it up too fast to know.
Notes
Use the rest of your box of silken tofu in a smoothie for extra creaminess and protein, or in this Fruit Pizza.
