Tips & Variations

FAQs
Can I use canned tuna in oil instead of spring water?
Yes, you can use tuna canned in oil for a richer flavor, but drain the oil well to avoid making the sweet potatoes too oily.
What can I substitute if I don’t have Greek yogurt?
You can use sour cream or plain yogurt as a substitute for Greek yogurt, though Greek yogurt is thicker and adds a creamier texture.
