For vegetarian filling, rinse and drain a can of black beans. Place in a bowl with salsa and taco seasoning and stir. Microwave, covered, for 2-3 minutes, until beans begin to pop. Stir. The mixture should be somewhat thick and spreadable. If still loose or watery, microwave a little more and stir. Use this mixture to replace the meat filling in the layers.
