Cut the chicken breast into long, thin strips and thread them onto wooden or metal skewers.
In a small bowl, whisk together the almond butter, coconut milk, tamari, minced garlic, grated ginger, lime juice, sea salt, and black pepper until smooth.
Place the chicken skewers in a shallow dish and coat them thoroughly with the almond-coconut marinade, then refrigerate for 20 minutes to let the flavors meld.
Preheat a grill pan over medium-high heat and lightly grease with a touch of high-heat oil if needed.
Grill the skewers for 4 to 5 minutes per side until the chicken is cooked through and shows beautiful charred marks.
In a separate small bowl, whisk the honey, rice vinegar, and red pepper flakes together to create a quick, clean sweet chili glaze.
Serve the hot skewers over a bed of fluffy brown rice alongside the fresh cucumber slices for a cooling crunch.
Drizzle the prepared sweet chili glaze over the skewers and rice immediately before serving.
