Remove the top of the jalapeno, slice in half and remove the seeds. Peel and seed the avocado. In a small blender add the jalapeno, avocado, lemon juice and sea salt and blend until creamy. Add more lemon juice or a touch of water for a thinner sauce if you prefer.
Warm the shells, and load up with the salad ingredients.
Drizzle or dollop sauce on top of tacos, and top with a generous pinch of Hemp Hearts, enjoy!
