Spicy Grilled Chicken

Sorry I haven't posted in a while. I just began working full time out of the house and haven't had much time to cook or post. I made this grilled chicken recipe last week and we loved it. I didn't use the lime zest as we didn't have one. It had a slight kick to it but not overwhelming that the kids couldn't eat it.

1/3 C. vegetable oil
2 Tbls. lime juice
2 cloves crushed garlic
1 1/2 tsp. oregano
1/4 tsp. red pepper flakes
1 tsp. salt
1/4 tsp. ground black pepper
6 skinless, boneless chicken breast halves cut into cubes

Mix the oil, lime juice, garlic, oregano, red pepper flakes, salt, and black pepper. Add chicken, and turn to coat. Cover, and marinate in the refrigerator for 1 hour, turning occasionally.
Preheat grill for medium-high heat.
Lightly oil the grill grate. Drain and discard marinade. Grill chicken for 6 to 8 minutes each side, or until juices run clear.
