This is creamy without the cream...or, oil. Brace yourself. It's not traditional Nicoise but I hope that it is close enough for your enjoyment. Serve this over or, beside traditional Nicoise collection of ingredients: hardboiled egg, tuna, steamed potatoes, green beans, tomato, and lettuce or, make your own salad of whatever veggies you can dream up!
Large Bunch of basil (About 2 cups packed 4 cups unpacked)
2 Tbsp. Grainy Mustard (I use Maille brand)
1 Tbsp. soy sauce
1 Tbsp. fish sauce
1/2 cup cashews
1 Tbsp. white wine vinegar
2 Tbsp. lemon juice
1/4 cup water
Blend all ingredients in the blender until creamy dressing is formed.
