Tequila-Lime Chicken Brochettes
Cut chicken breasts crosswise on a slight diagonal into 3/4-inch-wide strips. Divide between 2 plastic refrigerator bags; add 1 cup marinade to each bag and seal. Turn bags to coat chicken evenly. Refrigerate 2 to 4 hours. While chicken marinates, cover and refrigerate remaining marinade.
In a small saucepan, bring reserved marinade to a boil; reduce heat and simmer 5 minutes, stirring occasionally. Strain through a fine sieve into a bowl.
Drain chicken in a colander. Thread onto presoaked bamboo skewers. Spray a grill pan with nonstick spray and heat until hot. Grill chicken skewers in batches, about 2 minutes per side, or until cooked through. Or broil skewers 4 minutes, turning once halfway through. Arrange on platters. Hit chicken with a squeeze of lime. Drizzle with cooked marinade; sprinkle with peppercorns and pumpkin seeds. Garnish with cilantro sprigs.
