G’day! How-ya-goin-allright?

I’m feelin’ Aussie so I thought I should speak as one…

do you fancy that? I love the way they talk!

…Soooo, my neighbor caught me trying to get a glimpse of her grocery bags…again…

Yes, I am interested to see where my neighbors shop for their food. I know…SO weird!

BUT it tells me a little something about their lifestyle. Like, if I see them carrying “Whole Foods” bags then I know that she must really, really care about her whole foods if she drove 70 miles for it. (We do live in booneyville, don’t we!?!) If she/he is carrying bags from the nearest convenience store, then she/he is very busy and paying 5-times more for their food doesn’t bother them. When I see a “Wal-Mart” bag filled with food items, I think penny-pinchers!

See? It makes sense, right?

Okay, I see… you wanna talk about some Fish Tacos with Creamy Lime Mustard Sauce! After all, that’s why you’re here. I know. I get you.

Well, here’s a story all about how my palate got flipped, turned upside down…and I’d like to take a minute just sit right there…I’ll tell you how I became …. a fan of fish tacos. I can’t rhyme. 😛

Yeah, I am not big on fish. But! But, but, but…smother it with some of this beautiful sauce that I like to throw together and I am game! Put it in a taco and I am flyin’ high!

All it is is some onions, garlic, lime, wine, and cream. That’s all you need to slather over your fish and fall in love with said fish. Most people like to use tilapia for their fish tacos, but I say use whatever fish you want. My choice is always salmon. Tilapia is a close second.

Got some tortillas? Good! Let’s cook!
