1 tbsp. canola oil
1 medium red onion, halved and thinly sliced
1 medium clove garlic, mashed to a paste with 1/4 tsp. salt
3/4 tsp. finely grated ginger
1/8 tsp. cayenne
1 lb. ground turkey
1 8oz. can tomato sauce
1/4 cup hoisin sauce
3/4 cup fresh cilantro leaves

Heat the oil; add onion and cook until softened.  Add garlic, ginger and cayenne and cook for about 1 minute.  Add the turkey and cook until no longer raw.  Stir in the tomato sauce and hoisin sauce, increasing the heat to medium high, until thickened (5-7 minutes).  Remove from the heat and stir in cilantro and lime juice.  Serve in buns.
