If you're looking to enjoy these scrumptious Cheesy French Pinwheels but need a gluten-free option, fear not! The key swap is the puff pastry. Nowadays, there are fantastic gluten-free puff pastry options available in the market that work wonderfully in this recipe. Look for brands that prioritize quality and texture, ensuring that even without gluten, the pastry puffs up beautifully and maintains that essential flakiness. Remember to check the labels on your other ingredients like mustard and salami to ensure they're gluten-free too.
