mango-cashew dressing

I learned this at the Health Getaway. They were demo-ing cashew-orange dressing but didn't have oranges so they used a mango and the started improvising. Here's my version which is sort of a hybrid:

Ingredients:

1 ripe mango

1 orange, peeled, remove seeds (optional)

1/4 cup cashews

1 Tbsp blood orange vinegar

lime zest

lime juice to taste (try 1/2 tsp to start) (optional)

a bit of cilantro or dill or chives if you have some (optional)
