Start by prepping your glass: Add crushed graham crackers to a small plate. Use a lime wedge to wet the rim of the glass, then dip the rim of the glass in the graham cracker crumbs, rolling from side to side until well coated.
Add all ingredients to a high powered blender: frozen banana, lime zest, lime juice, vanilla yogurt, milk, spinach and vanilla extract. Blend until smooth, adding more milk to thin, if necessary.
Taste and add sweetener if you feel it needs it, but personally I find that if you use vanilla yogurt then it’s sweet enough!
Pour into the prepared glass, top with whipped cream and a little shredded toasted coconut on top! Serves 1. Feel free to double the recipe to serve 2.
