6 Theories about Fish Tacos

When I was growing up, my grandmother had one of those decorative plates in her kitchen that said "Before I had children, I had six theories about having children. Now, I have six children and no theories".
Well, I too had theories and plans. (yeah, they are hilarious - no tv, no Disney princesses, no flavored milk, mommy never loses her cool. I know, I told you, hilarious). One of the things I was so appalled by was Jessica Seinfeld's book about hiding healthy food. True, I never read the book or even opened it but, I did see her on a morning show. On my high horse I would spout how I want my kids to love the taste of good, healthy good and hiding it robs them of that opportunity.
And, then, I had a three year old. The same 3 year old who woofed down a cheese and tilapia quesadilla last night. Oh, I mean a cheese quesadilla, just ask her. Yep, not only did I sneak fish in there - then, I lied. (will my mother of the year award come in silver or gold? silver would match the decor in my family room). My 15 month old gobbed up the tilapia on her plate. White flaky fish is easy to hide. Just flake and layer it with the cheese.
For the adults, we had fish tacos. My husband piled everything in his except the avocado. He says he does not like it. It could be true. Though he has never tried it outside of a California roll.

Fish tacos -
Fresh whole grain tortillas. (the fresher the better. Sorry if you live somewhere that you can't just stop and pick these up.)
Fish (I like tilapia for this. It is inexpensive and easy to find. For a list of sustainable, low mercury fish http://www.edf.org/page.cfm?tagID=15890 )
