Directions. 1  In a heavy-bottom 4-quart pot, heat butter and olive oil over medium heat. Saute leeks 5-7 minutes, until tender. 2  Add cucumber and chicken stock. Simmer until cucumber is softened (about 6-8 minutes). 3  Pour small batches of cucumber soup into a blender and puree until smooth.
Grill for 5-10 minutes, depending on how hot the grill is (you do not want the chicken to burn). Once you have a good sear on one side, move the chicken pieces to the cooler side of the grill.
To make BBQ tenders, brush with sauce the last 2-3 minutes of cooking. Preheat grill to surface temperature of about 450 which is medium high on most gas grills and medium on a hot gas grill. Clean and oil the grill surface well. Pat dry 6 (or as many as you need) chicken tenders. Trim the tendon as much as is easy to trim. In a mixing bowl, mix tenders with 1 T olive oil and 3/4 tsp of 7:2:2 (or 1/2 t of kosher salt, 1/4 tsp pepper and 1/4 t granular garlic powder). Place over direct heat. Grill until the chicken turns from a pink color to white along the edge (about 5 minutes). You will see the white moving up the sides.
