Rather than post a recipe, here is the basic idea of the dish. I started by parboiling baby yellow potatoes, and sauteing a sliced leek and some garlic in olive oil. I added cubed tofu and chickpeas, the potatoes cut into large chunks, and asparagus. I then added about 1/2 cup lemon juice and 2 tsp of dill, and then 2 cups of soy milk. After seasoning with salt and pepper, I blended flour in some water and added it to thicken the sauce.
Does anyone know how to make a creamy sauce with lemon? I assume there is a way to mix the two since I have seen vegan lemon cheesecake and lemon curd. Maybe it needs to be blended first and then added?
