In a large bowl, whisk together the flour, chia seeds, matcha powder, sugar, baking powder, baking soda, and salt.
In a separate bowl, whisk the egg, milk, vanilla extract, and melted butter or coconut oil until combined.
Pour the wet ingredients into the dry ingredients and gently mix until just combined. Do not overmix. Let the batter rest for 5 minutes.
In a medium bowl, combine the diced mango, pineapple, kiwi, lime juice, honey or maple syrup if using, and fresh mint. Set aside.
Heat a nonstick skillet or griddle over medium-low heat and lightly grease it.
Pour small portions of batter onto the skillet and cook until bubbles form on the surface and the edges look set.
Flip and cook the other side until golden and cooked through.
Repeat with the remaining batter.
Stack the pancakes and spoon the tropical salsa over the top before serving.
