Add strawberries, Greek yogurt, milk, honey, and vanilla to a blender.
Blend on high until completely smooth, about 45 to 60 seconds.
Add ice and blend again until frosty and thick, 15 to 30 seconds.
Taste and adjust: add more honey for sweetness or a splash of milk to thin.
Pour into 2 glasses and serve immediately. Garnish with a strawberry if desired.
Notes
For a protein boost, add 1.0 tablespoon chia seeds or a scoop of vanilla protein powder. For dairy-free, use almond milk and a coconut yogurt. Use frozen strawberries for a thicker smoothie and skip the ice.
