Soak your wooden skewers in water for at least 30 minutes, so they don't burn on the grill.
To make your marinade; in a medium bowl add fresh pineapple juice, coconut aminos, vinegar, ketchup, honey, ginger, garlic, chili flakes, and sesame oil. Whisk well.
Reserve 1/2 cup of this marinade (set aside for serving, untouched by the raw shrimp) then add the rest into a large glass bowl or ziplock together with the shrimp. Seal then shake or stir to combine well. Refrigerate to marinate the shrimp for 20-30 minutes.
Preheat your grill pan or an outdoor grill over medium heat. Skew the marinated shrimp onto skewers as shown.
Grill your shrimp over medium-high heat for 2 - 3 minutes on each side.
Meanwhile, drizzle or spray the bell pepper and pineapple with avocado oil or coconut oil. Sprinkle the bell pepper with smoked paprika, sea salt, and pepper.
On the same preheated grill, grill your bell peppers & pineapple for 2 - 3 minutes on each side, or until nicely charred and heated through.
To assemble your bowls, divide the cooked brown rice or cauliflower rice equally into 4 serving bowls. Top with the grilled bell peppers and pineapple. Serve with your shrimp skewers as shown.
Garnish with fresh cilantro and lime wedges and serve with the remaining (reserved - untouched) marinade sauce.
Enjoy!
