Living the Mixed Kitchen Life

Tonight, I ,anaged to get dinner on the table somewhere around the time that 3 of us were hungry.  It was nothing fancy.  Simply rice pasta (courtesy of Trader Joe's), and a scramble of eggs with carmelized onion and a few greens of varying kinds for those who wanted and could eat them. 
Bumblebee ate early, and was requested next door, where I offered to walk her. 
"Don't poison my dinner," I teasingly warned Penguin and my dear husband. 
Amidst their protests that they love me, would never poison me, did I even have to remind them? I headed out the door with Bumblebee, gave her a kiss, told her when to return and to be good, and returned home. 

Writing the prior paragraph took longer than the entire process. 
However, when I stepped into the kitchen, Penguin was staring at her plate and my husband was at the sink.  My place was empty. 
"What happened?" I queried, trying to see the joke in the matter and thinking that it really looked like my dish in the sink that was being furiously scrubbed. 
Dh turned and gave me the look that I deserved to give him. 
"One thing.  You asked me to do one little thing.  And I couldn't do it!"
"I was only gone two minutes!" I exclaimed, more confused than upset.
"I know!" 
At this point Penguin couldn't help bursting into laughter at the ridiculousness of the situation (and probably scared that her parents were going to start a full fledged fight at the dinner table)  And confessed that they'd poisoned my plate accidentally. 
Apparently he reached across the table to help Penguin pour some sauce, and a small amount splashed onto my plate. 
If we were a normal household, I'd have had a sprinkle of undesired flavoring, and ignored it. 
But with food allergies?  It meant an extra plate and eating tomorrow's leftovers. 
Dh was really upset with himself, but like I told him...better to acknowledge the error and not make me sick (I might have suspected eggs!  Or onion!  Or the cheaper TJ pasta!  Or heaven forbid the handful of chocolate chips I treated myself to after dinner) 
It disturbs us because neither of us like the message we send our kids when a crumb, or a drop, of something unintentional happens to land in an unexpected area.  But, the kids aren't satisfied on a corn free diet, and my husband doesn't really want to restrict his diet that far.  And asking makes me feel bad. 
So, we'll continue to be supervigilant.  I'll try not to lose my temper when accidents happen (I try...And this time there was plenty to eat so I really wasn't upset!)  And he'll have to forgive himself when things do.  The real point is that we need to continue to be aware and avert disaster.
