Cheesy Pleasing Cauliflower

I adore my Big Guy.  For many reasons, he's tall and can reach things I can't.  He is super with our finances (and I am thankful).   He makes me laugh.  And just to shorten the list, he came into our relationship with some kick butt kitchen items and great recipes!  This is one of them!
Don't laugh - but this recipe doesn't really have a name.  Maybe you can pick one for it.

Ingredients needed:
Head of Cauliflower
1 cup shredded Cheddar cheese
1/2 cup to 3/4 cup of mayonnaise
3 tablespoons of mustard (yellow or Dijon)

Take leaves and core off bottom of cauliflower.  Put in microwavable bowl that is large enough for cauliflower to sit inside flush.  Add 1/2 cup of water and cover with plastic wrap - to create a "steamer".  Place in microwave.  Cook till tender.  In my 12+ year old microwave, it takes 10-12 minutes depending on how large of head of cauliflower.  Remove plastic wrap and drain water.
In a separate dish, mix together mayo and mustard.  Spread over steamed cauliflower to cover.  Sprinkle shredded cheese over top.  Place back in microwave to melt cheese.

The mayo mustard mixture heated with the cheese and steamed cauliflower - So Yummy!  Teen loves it!
