Shady Brook has been selling them in this area for about a year and they are about 1/4 to/2 an inch thick. I grilled them an very low heat after marinading them from Cooks recipes I found on Goggle.
1/2 c chicken broth, 1/2 c soy sauce, 1/2 c rice vinegar, 3 cloves garlic, brought to a boil, then cool to room temp. 1/2 went into zip bag with chicken to marinade for 1/2 hour. The other half added 1 1/2 tsp of sugar brought to a boil the added a slurry of 2 tsp of corn starch and 1/2 tsp salt, 2 Tbs of water, cook till thicken. Cooked on preheated grill on lowest setting 5 min. one side 4 min other side. Placed the chicken on a bun, toped it with the sauce, lettuce and tomato. It was rally very good.
