Combine peanut butter, soy sauce, lime juice, red pepper flakes and canola oil in a medium bowl. Whisk until well combined. Add additional lime juice or oil if it needs some thinning.
Sprinkle chicken with salt and pepper. Heat grill to medium-high heat. Grill chicken until done, about 3-4 minutes per side. After flipping the first time, spread a thin layer of the peanut sauce over top of the chicken.
When chicken is done, remove it from heat and serve with peanut sauce for dipping.
