In a medium skillet, cook the sausage over low heat for 10 minutes, shaking frequently. Remove from the pan, drain on paper towels and set aside. Place the frisee, tomatoes, cheese and cooked chorizo in a large bowl and drizzle with the vinaigrette. Toss well to coat and serve on chilled plates with rings of red onion on top.
Combine the garlic, vinegar, honey and lime juice in a blender and puree until smooth. With the motor running, slowly add the oil until emulsified. Season with salt and pepper.
To roast garlic: Preheat oven to 350 degrees. Drizzle a tiny bit of olive oil over unpeeled garlic cloves, and wrap in aluminum foil. Place on a cookie sheet and bake about 1 hour, or until soft throughout. Set aside to cool, then peel.
