Butch, if you have a favorite salsa, guac is easy peasy...peel a couple of nice sized ones that are just beginning to give under a squeeze in your whole hand, toss the pit, duh.
Put 'em in a bowl, an add a tablespoon or less as you like it of lemon or lime juice. Add maybe 1/2 to 1 cup salsa, to taste, and mash the whole mess up to a chunky texture.
Done. Dip with chips, spoon over any Tex-Mex entre, add over your omlette, toss with a salad, on a burger...endless options.
