There is something about melted cheese that turns any sandwich into gooey goodness.  As a kid, sandwiches with melted cheese were synonymous with summer vacations. Toasted cheese sandwiches, grilled ham and cheese sandwiches, and tuna melts were commonly on the summer lunch and dinner time menu. Years later, I discovered crab melts–the upscale, elegant version of the tuna melt. I was instantly in love with the creamy, melty treat.

Crab Melt Prep

Of course, sandwiches are hard to do on a low carb diet. Thankfully, not only does the portobello mushroom make a perfect substitute for bread, but its subtle flavor complements the crab and the cheese.  Portobellos even add to the presentation of the classic crab melt.  These mushrooms piled high with crab salad and melted cheese make a picture-perfect meal suitable for an elegant luncheon.

I pre-bake the mushrooms until they are starting to soften so they are completely tender when the cheese is melted.  This pre-bake is done with the concave side (gill side) down so the juices drip off.  Allowing the juices to drip off helps the mushrooms not get soggy.
