Dice the red onion, bell pepper, and tomato into 1/2-inch pieces. Combine with the diced mango in a medium bowl with chopped cilantro, lime juice, and salt; cover and refrigerate.
In a small saucepan, add the black beans (undrained) with the diced tomato, purple onion, and seasonings. Simmer on medium-low heat.
Cube the chicken into 1-inch pieces, coat with seasonings, and set aside.
Wear gloves to handle the habanero pepper; remove seeds and add half to a blender.
Add the diced mango, garlic powder, lime juice, honey, and salt to the blender and blend until smooth. Set aside 1/4 cup of the sauce.
Heat a skillet over medium heat and cook the chicken until the internal temperature reaches 165°F (about 7-9 minutes).
While the chicken cooks, heat the cooked rice and mix with a drizzle of lime juice, chopped cilantro, and salt.
Add the remaining 1/2 -3/4 cup of the Mango Habanero Sauce to the skillet and cook for an additional 2-3 minutes until thickened.
Mix the set aside 1/4 cup of the sauce with the plain Greek yogurt and whisk until smooth. Add water until you get the consistency you want!
