Good sprinkled with Mexican queso fresco, goat cheese or blue cheese.
1. Cook the chorizo and onion. In a very large skillet, cook the chorizo over medium heat for 4 or 5 minutes until it has rendered a good amount of its fat. Add the onion and continue cooking until the onion has started to soften but is still crunchy, about 5 minutes.
2. Create the dressing, finish the salad. To the skillet (still over medium heat), add the oil, vinegar, sugar and 2 tablespoons water. Mix well, taste and season with salt, usually about 1/2 teaspoon. Pour the warm mixture over the spinach, add the jícama, mix well and serve.
