Prepare the ingredients. Cook the vegetables—I use the microwave, since each one takes about 2 to 3 minutes. Start with 1 1/2 minutes, then add 30 seconds at a time until they reach your desired doneness. Check often to avoid overcooking and making them mushy. Mix the mayonnaise and sour cream with salt and pepper to taste.

Combine the chicken with the mayonnaise and sour cream mixture. Add the cooled vegetables.

Gently mix so the vegetables don't get mushy. Serve on tostadas or with crackers, along with a green salad.
