The taste of the tarragon will become more pronounced after mixing the ingredients. Use a little less than you think you'd like and let the salad sit in the fridge for an hour for the flavors to develop. After an hour, stir and adjust seasonings.
3 large chicken breast, trimmed
3 garlic cloves, sliced
1 tsp. Tarragon, dried
1 C. mayo
1 C. sliced grapes
½ C. chopped walnuts
Slice the chicken breast into 4 or 5 pieces. Bring a large pot of water to boil. Add chicken and garlic and cook until cooked through. Drain the chicken and discard the garlic. Shred or chop the chicken into a large bowl. Add tarragon, mayo, grapes, walnuts, salt and pepper. Mix well. Add more mayo for desired consistency.
