Typically, not much can be said of two slices of bread sealed together with a wedge, sliver, or hunk of cheddar. The grilled cheese is the simplest of sandwiches: for college students, a quick fix in a makeshift kitchen; for parents and children, an easy bite on the go. But for Ms. Cheezious founders Brian and Fatima Mullins, it's a culinary canvas. Their 2-and-a-half-year-old food truck, decked out with a larger-than-life sexy caricature of Ms. Cheezious herself, winds through the streets of South Florida whipping up creative takes on the croque-monsieur. Monday through Saturday, the food truck can be found stationed at different special events and food truck rallies in Miami-Dade, Broward, and Palm Beach. The truck features a special cheesy creation each week, but several bestsellers are constants on the menu. They range from the Crabby Cheese Melt ($8), a creamy crab spread on cheddar-lathered sourdough, to the Grilled Harvest ($7), a sweet-and-sour pairing of Havarti cheese and sliced apple. Patrons can also build their own sandwiches, and once you've decided on a cheese style and extra toppings (such as shaved ham, prosciutto, or bacon), the truck's zesty tomato soup is the perfect accompaniment.
