grilled spicy pork skewers & yogurt sauce

we buy our free range meats from creswick farms near grand rapids, mi, once a month. so far, i was at a lack of new ideas for the ground pork that's been in the back of our freezer all month long. then i came up with grilled spicy pork skewers, kind of like a pork variation of the middle eastern "kefta" & a good deviation from grilling hot dogs & burgers.
for the skewers:
a. if using wooden skewers, pre-soak in cold water for at least one hour
b. mix by hand 1 lb. ground pork, 1 tsp. ground cumin, 1/2 tsp. ground coriander, 1/2 tsp. ground hot chile pepper, 1/2 tsp. chile flakes, 1 tsp. salt, 1/2 tsp. black pepper, & 1/3 cup fine breadcrumbs until all is incorporated evenly throughout the meat
c. form 1 1/2 inch balls and then elongate them a bit before skewering through the center
d. place skewers on a pre-heated grill (high heat, 400F) or under broiler
e. let cook 3-5 minutes on each side or until cooked though (internal temp 160F)
f. remove from grill and let rest for a few minutes before eating

for the yogurt sauce:
a. start with 1/2 cup plain cultured yogurt
b. stir in 2 tsp chopped fresh mint, 1 tsp chopped fresh cilantro, 1 tsp fresh lemon juice, 1 tsp ground cumin, and salt and pepper to taste
c. use liberally to accompany skewers
