Add the pineapple chunks, banana slices, Greek yogurt, coconut milk, and ice cubes to a high-speed blender.
Blend on high until the mixture is smooth and creamy, about 1–2 minutes.
Taste the smoothie and add honey if you prefer it sweeter; blend again to combine.
Pour in the lime juice and pulse once or twice to mix without over-blending.
Check the consistency—if it's too thick, add a splash more milk and blend briefly.
Pour into glasses and serve immediately while cold and frosty.
For extra flair, garnish with a pineapple wedge or sprinkle of toasted coconut.
