Abstract: In this talk I will show how to use Lagrangian surgery to construct a tropical Lagrangian submanifold in (C^*)^n from the data of a dimer on a torus. We will use Haug's antisurgery technique to build ``mutations'' of this Lagrangian, and see how this operation is reflected in certain manipulations of the dimer. Finally, we will discuss how the Floer theoretic support of this Lagrangian is related to Treumann, Williams and Zaslow's work on the Kasteleyn operator and mirror symmetry.
