I'm with you on the dislike of cooking. It's just not fun for me. But, that's ALL cooking...I don't have a "diabetic" supper plan. I make simple modifications to make the meals more friendly for me or I choose not to eat certain things I serve the family. (Like corn...it's used to FATTEN up animals so I try to avoid it. But, my husband likes to make corn on the cob so I just skip it when he grills).
I was diagnosed Type 1 a year ago and am starting to leave the honeymoon stage. It's tough. I'm really working on better meal planning. It's hard because I have 4 kids and my husband has disordered eating. I can't keep the foods I need in the house (and I've resorted to locking up some items but some things have to be refrigerated). We eat out/order in a lot but it's not good for our health or waistlines so we are (well, I am!) working on changing some things.
My goal is to start cooking 3 nights a week and having left overs. In the past it's worked well if I post a menu/schedule so everyone knows what to expect. For me, it's 99% planning! If I have a plan, I can follow it. The kids love tacos (I do mine on a salad) and I have started making spaghetti squash as a pasta options. (I still make regular pasta for the kids but I'm just as happy with the squash). I'm working on making "real food" items like some of the recipes mentioned in this thread. Roast with veggies, salad, etc. I think it's much healthier and it's easier to calculate carbs when we use the whole foods versus casseroles, etc. I also, am working on cleaner eating/organic, etc and am reading a Paleo book. It may be a bit too intense for me but I am working on simple meals that are healthy, easy to prepare and the everyone will enjoy.
I think it's all about progress not perfection. See if your wife will help you with meal planning ideas. We have a "I cook, you clean" rule which is helpful as well. I've also tried to engage the family in the cooking process. My husband enjoys cooking on the grill so that's a good option as long as I buy the meat. I don't like the qualify he selects sometimes.
