Preheat the oven to 400 F. Prepare a baking sheet with parchment paper.
Place plantains in a bowl and mix with the coconut oil, coating the plantains thoroughly. Sprinkle with sea salt then lay the plantains in a single layer on the sheet pan.
Bake at 400 F 30-35 minutes until golden and crisp, flipping plantains half way through.
While plantains bake, preheat a medium skillet to medium heat.
Add the ground beef and remaining seasonings to the skillet.
Use a wooden spatula to break up the meat as it cooks, turning frequently until it browns.
Using a colander, drain the beef.
Place the beef back in the skillet and add diced bell peppers. Stir to combine and cook 3-4 minutes until peppers are slightly tender.
Remove from the heat and serve with baked plantains and optional ingredients as desired.
