Cut open the avocado. Remove the pit. Slice the pulp into thin slices, scoop it from the shell, and arrange the slices over the lettuce.
1 avocado
Peel the mango, cut the flesh into thin slices, working around the pit. Slice these slices crossways, so they become slivers. Arrange them onto the salads.
1 mango
Add diced red onion, grape tomatoes, chopped cilantro, and toasted almonds.
To toast almonds, preheat an oven to 350 F (177 C). Spread the almonds out on a baking sheet, and toast them for 2 to 3 minutes, watching carefully. Pull them out as the almonds are just starting to turn brown around the edges. A toaster oven is great for this, if you have one.
