Blend 2 eggs and 2 green plantains in the blender, until smooth and creamy. Set aside.
Cook 4 strips of bacon over medium-low, flipping once, until done. Pour bacon fat into a small dish and use as needed for cooking. Set bacon aside on a paper towel-lined plate.
Cook 4 eggs over easy. Optional: Crack eggs into the ring of a mason jar lid to cook eggs into circular patty. If using cheese, add a slice of cheese the tops of the eggs, after flipping. Set aside with bacon.
Add a bit of bacon grease or other fat to the skillet, and ladle plantain-egg batter into the pan into 4 pancakes. Cook until the top starts to bubble and dry out and underside is lightly brown. Flip and continue to cook, until done. Repeat to make 4 more pancakes.
Sprinkle the tops of the pancakes with sea salt.
Add pancake buns to serving plates and top with lettuce, egg, bacon, avocado slices and a dash of hot sauce (if using). Top with remaining pancake buns.
Serve with a side of sliced grapefruit.
