I claim the ornamental design for a microwave cooking device, as shown and described.
FIG. 1 is a perspective view of a microwave cooking device, illustrated with a plunger thereof in a lowered position, showing my new design;
FIG. 2 is a front elevational view of the invention, illustrated with the plunger in a raised position;
FIG. 3 is a rear elevational view of the invention, illustrated with the plunger in the raised position;
FIG. 4 is a left-side elevational view of the invention, illustrated with the plunger in the raised position, the right-side elevational view being a mirror image thereof,
FIG. 5 is a top plan view of the invention; and,
FIG. 6 is a bottom plan view of the invention.
The broken lines showing a food item in FIG. 1 are included for the purpose of illustrating a microwave cooking device in use, and form no part of the claimed design.
