With these snowflakes, only the cheese melts. Fold a flour tortilla in half, then in thirds. Snip out shapes, unfold, and use as the top of a quesadilla.
FOR A JACK-O'-LANTERN VARIATION: Finely shred raw broccoli and sprinkle onto a sun-dried-tomato tortilla; cover with shredded cheddar cheese and top with another tortilla shaped like a jack-o'-lantern. To make the face, cut out triangle eyes, nose, and a mouth shape with a paring knife. You can also use kitchen shears. A plain tortilla works too, but we like the orange color of the sun-dried-tomato tortillas. Bake in the oven on a lined sheet until the cheese melts (6 to 8 minutes).
