Common Questions and Answers
Q: Can I make this recipe ahead of time?
A: Yes! You can prepare the tuna salad up to 2 days in advance and store it separately from the peppers. Assemble just before serving for the best texture.
Q: How do I prevent the peppers from tipping over?
A: Try slicing a very thin piece off the bottom of each pepper half to create a stable base, being careful not to cut through to the inside.
Q: What’s the best type of tuna to use?
A: I recommend chunk light tuna in water for this recipe. It has a milder flavor and lower mercury content than albacore, plus it’s usually more budget-friendly.
Q: Can I use regular yogurt instead of Greek yogurt?
A: While regular yogurt will work, I recommend straining it first to remove excess liquid, or your filling might become too watery.
Q: How do I make this recipe more kid-friendly?
A: Try using sweeter bell peppers (red, yellow, or orange), add a bit of grated carrot for natural sweetness, and let kids choose their own toppings.
