Place the pineapple, strawberries, and raspberries in a food processor. Blend until smooth.
Add the honey and Greek yogurt. Blend once more to combine.
Pour the blended fruit into Popsicle molds, add the Popsicle sticks and freeze overnight.
When removing the Popsicles from the molds give them a few minutes to thaw around the edges so they come out easier.
Notes
Chop the pineapple- You'll want to make the pineapple pieces about the size of the strawberries to make it easier for the food processor to puree them.
Pay attention to the fat content of the yogurt- If you want to keep this recipe healthy, use lower-fat yogurt. For a creamier popsicle, use full-fat yogurt.
Let them thaw a bit- When removing the popsicles from the molds, give them a few minutes to thaw around the edges so they come out easier.
Loosen them with warm water- If the popsicles are stubborn coming out of the mold, run some warm water over it to loosen them up.
