One of our favorites.. from a restaurant that is so sadly closed now.. we decided to try to make this since we loved it so much. C T makes the crab- we load it up on top of the chips, with langostinos, black olives or whatever topping you love. You could add shrimp or crawfish. The toppings are endless. We add a colby/monterey jack cheese on top & then stick it in the oven til melted. It doesn't sound like a typical nacho combonation- but it is SUPER good!!!
