Cut your clean boneless chicken breast into bite-sized strips. Season with salt and pepper on all sides.
Keep a frying pan ready and cook the chicken on all sides soft. Keep aside to cool.
Shred your lettuce leaves into bite-sized pieces.
Cut your tomatoes into half.
Place the salad, tomatoes, and chicken together into a bowl.
In a small mixing bowl add the mayonnaise, the curry powder, and the vinegar.
Mix the curry mayo dressing together.
Keep the mayo and salad ingredients separate until you plan on eating it so that the greens stay nice chunky. Mix all together once you are ready to enjoy your curried chicken salad.
