Daiya melts and is actually a yummy soy-free cheese alternative. It's pretty amazing. We like the Italian Blend; it's not as buttery as the Cheddar. I usually order it from Vegan Essentials
So, anyway, last night we had Daiya Spinach Quesadillas. This time we used corn tortillas, and it seemed to bring out the flavor more than the flour. Plus, corn tortillas are healthier, so it's a win-win.
Basically, I think everyone should at least try Daiya. Be adventurous!
