Cook rice according to package instructions (as a general rule, boil 2 cups of water for every 1 cup of rice).
To make the mango salsa, peel and finely chop mango. Place in a small bowl.
Add 1/2 a green pepper, 1/2 a red onion and 1/3 cup cucumber, finely diced. Add 2 tbsp chopped cilantro, salt and pepper to taste and juice of one lime. Set aside.
In another bowl, mash 1 ripe avocado.
Add remaining 2 tablespoons of cilantro, and salt and pepper to taste, and juice of 1/2 lemon. Set aside.
In a small bowl, combine 1/2 tsp each of paprika, cayenne, granulated garlic, thyme, basil and black pepper.
Melt 1 tbsp of butter and brush on top of salmon.
With a clean hand, rub salmon with spice mix so that the top is completely covered.
Heat a non-stick pan over medium heat. Once hot, melt remaining tbsp of butter and place salmon, skin-side up.
Cook for 3-4 minutes, before flipping (this will depend on the thickness of your salmon).
Flip salmon over and cook for another 5-6 minutes. I sliced the salmon into smaller pieces later so if you're worried it isn't done, cut it in the middle and take a peek.
Remove salmon from heat and let stand for 2-3 minutes.
To assemble bowl, fill with half rice and half greens. Add mango salsa, guacamole and black beans. Top with salmon. Enjoy!
