In a large pan over medium heat, cook bacon until slightly crispy. Set aside.
Drain excess bacon fat, leaving behind about 1-2 tablespoons.
Cut off the ends of the plantains and remove the peel. Thinly slice the plantain lengthwise into 3 slices. Repeat with other 2 plantains.
Add plantain slices to bacon fat pan and cook about both sides for about 2-3 minutes until they are slightly browned. Set aside.
In the same pan, add minced garlic clove, ground beef, onion and salt and pepper. Cook until meat has broken down and completely cooked through.
Now for the stacking of the casserole, you can do this any way you’d like.
Place 3 plantain slices on the bottom, then 2 slices of bacon on top, then a couple spoonfuls of the ground beef mixture. Repeat two more times on top of the ground beef mixture.
Put in oven and cook for 12-15 minutes. Let sit for about 5 minutes.
