Trim the bottom end of the asparagus and blanch with boiling water.
Blend the mustard and mayonnaise in a small bowl. Divide and spread the mustard mixture evenly on the large bologna slices. Wrap one asparagus spear in each bologna slice. Place the slices in a single layer on a round microwave platter or plate. Cover lightly with paper towels.
With the microwave on MEDIUM, cook for 1 minute or until hot; rotate the plate one-half turn after 30 seconds.
