How To Be A Housewife: Eggplant Pizza

It's the summer and I usually try some new foods.  This summer I've been slacking though and haven't really done as much.  After realizing that I gained ten pounds from March 2015 to October 2015 I have somewhat realized that I need to make some lifestyle changes.  My goal for the rest of the year is to try to eat healthier and I'm trying to make that change this week.  So yesterday I went to Kroger and purchased an eggplant for $0.98.  I've never had eggplant before today and I was pleasantly surprised at how good it was.

Ingredients
