To make the vinaigrette:
On a preheated comal, skillet, or griddle set over medium heat, toast the güero chile for 6 to 8 minutes, flipping as needed, until skin is charred and chile is softened. Remove from the heat and remove stem and seeds, if desired.
In the jar of a blender, add the roasted chile, habaneros, lime and lemon juices, vinegar, olive oil, honey, avocado, salt and pepper. Puree until completely smooth. Scrape into a bowl.
To assemble the salad:
In a salad bowl, add the lettuce, jicama, and half of the grapefruit and orange supremes. Toss with some of the dressing until completely covered but not soaked. Add the remaining grapefruit and orange supremes on top. Add more dressing as needed.
