fish tacos with onions and peppers, avocado and cheese

A lot has happened in the past week.  I threw out my back and was down for the count for 3 days and as soon as I was able to walk 3 steps and not wince in pain I needed to jump into the kitchen and prepare a picnic meal for my friend Elaine Tolson’s Royal Lady Retreat .  I had the most amazing time with the ladies on Saturday…we laughed, we glittered, we ate and then we repeated…multiple times.  It was a gorgeous day that will last a lifetime in my good thoughts.  My only regret of the day – leaving my camera in my truck the entire day.  Not one picture.  Can you believe it?  No, me either.  Luckily Elaine posted this one on Facebook and I snagged it for this post.  Thanks Elaine!  🙂

As you can imagine, Sunday came and I was rejuvenated, but exhausted.  I sat on the patio for what seemed to be 49 hours.  It was heaven.  Today it was time to get back to life as I usually know it…pain free and whipping up deliciousness for my family.  And in keeping with our vow to be better at eating (shhh…let’s not talk about the carrot cake) we had Tilapia Tacos tonight.  And may I say….they were great.  The kids, who usually want to slop on a carton of sour cream and a pound of cheese, were content without either.  Give them a shot.  They are tasty, quick and healthy.
