I whipped up some of Isa Chandra Moskowitz's Chickpea-Hijiki Salad Sammiches and topped them with Mozzarella Style Daiya. For the last step I broiled them in the oven for 5 minutes.
As you can see, the Daiya melts and browns as if it were dairy cheese. If you want to get REALLY lazy you could buy some English muffins and spaghetti sauce and make mini pizzas. And if you are REALLY REALLY lazy, Daiya is already in some prepackaged Vegan foods.
Amy's Rice Macaroni with Daiya
Gardein Marinara Chick'n Good Stuff with Daiya
The Higher Taste Vegan Supreme Burrito with Daiya
Out of these three the only one I've had is The Higher Taste Burrito. It was amazing as I'm sure the others are.
