Preheat your oven to 375°F and line a small baking sheet with parchment paper.
In a small bowl, combine the lump crab meat, low-fat cream cheese, and garlic powder until smooth.
Place the wonton wrappers on a flat surface, spoon the crab mixture into the centers, moisten the edges with water, and fold into triangles to seal.
Bake the wontons for 10-12 minutes until the edges are golden brown and crispy.
While wontons bake, heat avocado oil in a skillet over medium-high heat and sauté the cubed chicken breast until browned and cooked through.
Add the bell pepper and onion to the skillet, cooking for 3-4 minutes until they begin to soften.
Whisk together the coconut aminos, rice vinegar, honey, and tomato paste in a small jar, then pour the mixture over the chicken and vegetables.
Stir in the pineapple chunks and simmer for 2 minutes until the sauce thickens and coats the ingredients.
Serve the sweet and sour chicken over the cooked jasmine rice, garnished with green onions, with the baked crab rangoon on the side.
