If limes could die and go to heaven, they would find themselves in owner Teresa Trevino's Key lime pie. This small, family-owned catering company in Mesquite has quietly made its mark among local schools and businesses, but its secret weapon is this dessert. With a whipped instead of gelatinous filling, it is as if limes ascended into the sky, evaporated into a cloud and then fell to earth landing in a pie crust. Yes, it's that good! Enough so that Trevino won't reveal the recipe. How about them apples? Oops, wrong fruit.
