Leeks, and red and yellow onions start in this savory, hearty pie. They 're sauteed together with white wine, and then combined with eggs, feta, parsley, tarragon and dill. This luscious filling is then poured into a tart pan lined with bread crumbs. The filled pan is then garnished with sliced tomatoes, and a sprinkling of parsley and bread crumbs. Bake, cut into wedges and serve.
