- In a small bowl, mash avocados with lime juice. Add salt and pepper, to taste.
- In a separate bowl, stir together crabmeat, mayonnaise, ½ teaspoon salt and ¼ teaspoon pepper.
- Arrange bread on a baking sheet. Divide avocado evenly among slices, and then top with crab mixture. Finish each slice of bread with 1 slice of tomato and 1 slice of cheese.
- Broil until cheese is golden brown, approximately 3-4 minutes (but keep a close eye on it because it might be done even faster).
