I had trouble selling the healthier stuff too. Had a couple cool salads (take on green papaya, a quinoa salad) and neither sold to save a trees life. I do have a relatively healthy cornmeal crusted avocado taco with veggie quinoa, miso special sauce and roasted tomato salsita and it sells really well. With corn tortillas its GF so it's all in one superstar when it comes to that. Otherwise no one wants anything to do with healthiness.
