Bring 1 ½ tsp of the curry powder and 2 inches of water to a simmer in a medium straight-sided pan. Add chicken and poach for 12 minutes or until cooked through. Cool slightly, and then chop into ½ inch pieces. Cool completely.
Meanwhile, slice tops off tomatoes and set aside. Scoop out tomatoes and turn upside down onto paper towels to drain.
Place remaining 1 ½ tsp curry powder in a small glass bowl. Microwave 1 minute, until fragrant. Combine with chicken, mayonnaise, and raisins/Craisins.
Place almonds in a second small glass bowl. Microwave 45 seconds.
Add almonds to chicken mixture, along with ¼ tsp. salt and the pepper.
Flip over tomatoes and sprinkle with remaining 1/8 tsp. salt. Fill with chicken salad and replace tops, if desired.
