Combine all ingredients in a medium-sized skillet.
Heat the skillet to medium-high temperature.
Cook the mixture for 7-8 minutes, stirring occasionally, until the vegetables are thoroughly heated.
Adjust the seasoning, adding extra salt and pepper to taste, if desired.
Serve immediately and enjoy!
Notes
For quicker cooking, thaw the frozen vegetables prior to cooking. This can be done either by running them under warm water until completely thawed or by placing them in the refrigerator for at least 8 hours in advance.
