Make the yogurt dip: In a bowl, stir together Greek yogurt, honey or maple, vanilla, lemon juice, cinnamon (if using), and a pinch of salt. Taste and adjust sweetness or lemon. You want it creamy, tangy, and lightly sweet.
Prep the fruit: Rinse and dry everything well.
Slice strawberries, apple, and banana. Toss apple and banana slices with a little lemon juice to slow browning.
Toast the waffles: Toast until crisp on the outside. If you like, brush with a bit of butter and dust with cinnamon sugar.
Cut waffles into quarters or strips for easy dipping.
Arrange the platter: Spoon the yogurt into a shallow bowl. Swirl in a dab of jam or sprinkle granola, nuts, or seeds on top for crunch. Surround with fruit and waffle dippers.
Serve right away: The waffles taste best warm, and the yogurt is ideal cold and creamy.
Set out small plates and let everyone dip and build bites.
