I finally made Chef AJ's yummy sauce today and I concur, it is yummy! You can find the recipe and video here. I used a half-pound of dried white beans (soaked and cooked), which is more than 1 can, so I increased the other ingredients: 2 lemons, extra garlic, 3 Tbsp of mustard, 2 medjool dates. For garlic I used green garlic--that's early garlic, it's like chives. I blended the white parts, then added the greens at the end for a quick chop instead of blend. Since 1/2 lb of beans usually lasts me 3 days, I added enough water to fill 3 16-oz jars:
That will nicely cover 2 salads a day. I wonder what else I should put it on.
