Grilled Cumin Chicken with Fresh Tomatillo Sauce

I've never worked with tomatillos before, but I was really pleased with how they taste. If you've never heard of a tomatillo before, they are like a green tomato with a husk. The poor grocery store clerk didn't have a clue what these were when she came across them. First she asked me what they were. Then she asked me to spell it. Then the girl behind me started asking all about them and what you make with them. Then the man behind the girl that was behind me was huffing and puffing and probably about to start yelling at any second. Let's just say I was ready to get out of there and go home.
I was expecting the sauce to be spicy since it had jalapeno bits in it, but I guess I did a good job of getting all of the seeds out. The seeds you see in the picture are from the tomatillo.

Ingredients:
2 teaspoons olive oil
1/2 teaspoon ground cumin
1/8 teaspoon pepper
2 garlic cloves, minced
4 (6-ounce) skinless, boneless chicken breast halves
1/2 cup fat-free, less-sodium chicken broth
1/2 pound tomatillos
1/4 cup cilantro leaves
1/4 cup chopped green onions
2 tablespoons fresh lime juice
1/2 teaspoon sugar
1/4 teaspoon salt
1 garlic clove, chopped
1 jalapeno pepper, seeded and chopped
1/4 teaspoon salt
Cooking Spray

Directions:
Prepare grill to medium-high heat.

Combine the first 4 ingredients in a large zip-top plastic bag. Add chicken to bag; seal and let stand for 15 minutes.

Discard husks and stems from tomatillos. Combine tomatillos and broth in a small saucepan over medium-high heat; cover and cook 8 minutes. Drain and cool slightly. Combine tomatillos, cilantro, and next 6 ingredients (through jalapeno) in a food processor; process until smooth.

Remove chicken from bag; discard marinade. Sprinkle chicken evenly with 1/4 teaspoon salt. Place on a grill rack coated with cooking spray; grill 6 minutes on each side or until chicken is done. Serve with tomatillo sauce.
