I do almost all the cooking in our house. The biggest problem I have is my wife and kids are very picky, and I like big/bold/spicy food. I really enjoy cooking but I'm limited to about a dozen things that my whole family will eat reliably. That, and my wife is totally freaked out about food-born pathogens, so she'll only eat overcooked meat. I've finally gotten decent at making her a well-done but not too tough steak, but if I leave her in charge of the chicken or roast it always comes out super dry even in the crock pot. I'll ask her how she cooked it (she's a SAHM) and she'd put it in the crock pot on hi for 6 hours, then on low for 2-3 more hours.
I also love to do fish and seafood (love living in the Pacific Northwest for that). One of my daughters will eat mild fish with me - catfish, trout, cod, even salmon - but nobody else likes tuna or shellfish. Which is too bad for them because we have the most amazing local clams, oysters, shrimp and dungeoness crab (not to mention the salmon, trout, halibut and lingcod).
The past couple weeks, cooking for myself I've had sauteed Brussels sprouts and sauteed asparagus - toss in some onions and mushrooms, with a little salt, pepper and garlic powder and they were super sides.
Typically on weekends I'll make eggs for myself and the girls for breakfast while my wife sleeps in. Scrambled or fried, or sometimes even an omelet. They like to help as much as they can - cracking eggs and beating them, grating cheese, etc. They been showing more of an interest in helping me in the kitchen which I usually appreciate, as long as I'm not trying to stay on top of too many things so I can focus on helping them. And they're always so proud to tell their sisters and mom about how they helped make dinner.
