1. Prepare the marinade: In a medium bowl combine yogurt, garam masala, ginger, garlic, turmeric, salt, and jalapeno, if using. Add chicken and toss to coat. Cover and refrigerate while preparing salad.

2. In a large bowl, toss together lettuce, cabbage, tomatoes, radishes, cucumber, scallions, cilantro, and jicama; set aside.

3. Heat oil in a large nonstick skillet over medium-high heat. Add chicken along with the marinade and cook, stirring, until the chicken is just cooked through, 6 to 8 minutes.

4. Transfer chicken and pan juices to salad mixture and toss to combine. Drizzle with lemon juice and season with salt and pepper. Stir to combine.
