Make the tofu: Preheat the oven to 375 degrees F.
Combine all ingredients in a large bowl and mix well.
Using a small ice cream scoop, shape the tofu into dumplings, and place them on a non-stick baking sheet or one lined with silicon.
Bake for 30-35 minutes until the dumplings are lightly browned and firm.
Make the sauce: Combine the pineapple, vinegar, tamari, garlic, and dates in a blender. Process until smooth.
Add the pineapple mixture to a sauce pan and cook over medium-low heat for 5 minutes.
Add the arrowroot powder mixture and cook until the sauce is thickened, about 1 minute.
To serve: Place the tofu dumplings on a serving plate and pour the sauce over them.
