Step 1Spoon the yogurt into a cheesecloth-lined strainer and let drain for two hours.
Step 2Toss together the chicken and tandoori paste in a bowl and let marinate while the yogurt is draining.
Step 3Spray a large skillet with nonstick cooking spray, then spray the chicken. Cook the chicken over medium-high heat until browned on each side, about 5 minutes.
Step 4Spray a small skillet with nonstick cooking spray. Cook the onions, garlic and ginger over medium heat until tender, about 5 to 8 minutes. Spoon the onions over the chicken in the skillet.
Step 5Stir together the flour and drained yogurt until smooth. Stir into the chicken. Bring to a simmer and cook over low heat, stirring occasionally, until the chicken is cooked through, about 10 minutes. Spoon into a serving dish and sprinkle with the chopped cilantro and mint. Serve with lemon wedges.
