I've got a date coming over for dinner on Friday that I'd like to impress. He's a bit picky- no garlic, no seafood, no raw tomatoes. This narrows down most of my standards. I have 2 hours and/or a crockpot.
Fries and a burger.
I use toasted english muffins for the buns and make small burgers. Different, but not TOO different.
Normally can't go wrong with steak and potatoes and corn on the cob (if it's fresh).
It really depends on his aversions.
No garlic? Does he bite?
Make something together. When you make it yourself, you'll probably taste it - works for kids, too.
Take a look through Molly Wizenberg's book My Homemade Life about when she and her eventual husband were cooking for each other and together.
Three incredible recipes guaranteed to wow http://www.food52.com/recipes..., just leave out the garlic. http://www.food52.com/recipes...
what about a roast chicken? it's easy and always delicious (there are many wonderful recipes on this site). you could make a big salad on the side, or a more traditional vegetable like mashed potatoes or roasted veg. good luck!
