Oh oh oh! I also made a Cilantro-Lime Creme for the tacos, I made this up myself and I thought it was a key topping :)
ingredients:
1 box silken extra firm tofu (the cardboard box kind, not water packed)
1 Tb olive oil
juice of 1 lime
dash apple cider vinegar
1 tsp sugar
1 tsp salt
1/4 cup fresh cilantro
-blend everything until really creamy, i use an immersion blender for several minutes
