Step 1: Preheat grill to high heat.
Step 2: Combine oil and chicken; toss to coat. Sprinkle with pepper and salt. Place chicken on grill rack coated with cooking spray, and grill 6 minutes or until well-marked.
Step 3: Place 1 cup Rhubarb-BQ sauce in a large bowl. Add the chicken to the bowl, tossing to coat the chicken.
Step 4: Return the chicken to the grill, and cook, turning and brushing with sauce from the bowl until glossy and carmelized, about 12 minutes or until done.
Step 5: Melt butter in a large saucepan over medium heat. Add onion and garlic; cook 5 minutes or until the onion is tender, stirring occasionally. Add rhubartb; cook 3 minutes or until the rhubarb is translucent, stirring occasionally.
Step 6: Add 1/2 cup water, sugar, ketchup, vinegar, and chipotle chili powder; bring to a boil. Reduce heat; simmer 6 minutes or until the rhubarb is tender.
Step 7: Place half of the rhubarb mixture in a blender. Remove the center piece of the blender lid (to vent); secure blender lid on the blender. Place a clean paper towel over the opening in the blender lid (to avoid splatters).
Step 8: Blend rhubarb mixture until smooth. Pour into a large bowl. Repeat the procedure with the remaining rhubarb mixture.
Step 9: Return rhubarb mixture to the saucepan. Bring to a simmer; cook 1 minute or until hot. Stir in mustard and salt. Enjoy!
