You guys are all wrong.
Basically you guys are advising him to make a crock pot/oven bag meal that is going to be a little better than a HAMBURGER HELPER meal.
He asked for a ROMANTIC dinner suggestion!?!
Start with the UNUSUAL, not the normal. For example, get a couple pounds of frozen King Crab legs or some fresh or frozen lobster tails. Yes they cost a bit more, but they also make a statement to the better half that you are trying to make this a special meal. Second, they are EASY TO COOK. If you can boil water then you can cook crab legs! Lobster can be broiled, tossed on a BBQ grill, or boiled. Any man can handle that! Melt a little butter and you have the main course.
For some sides, consider something like grilled asparagas spears. Again, unusual, but so simple to cook. Take a bunch of fresh spears, trim off the root end, and toss them on a hot BBQ grill. Cook them lightly, turn them and remove them from the heat. That is it. You only need to cook them just enough to get some "grill marks" on them before turning them. Want to make them FANCY? Take some olive oil and drizzle it over the raw spears and gently rub in on them to lightly coat them, then sprinkle on some coarse salt. Or if you like them hot, add some red pepper oil or some coarse ground pepper.
Another good side would be noodles with butter, garlic and salt. You can fancy them up by using tri-colored noodles. Or by using an unusual noodle like gnocchi. Boil water, cook until done, rinse. In the cooking pot add butter, crushed garlic and liberal amounts of Morton's Natures Seasoning (which is basically salt, parsely, sugar and spices). As soon as the butter is melted put the noodles back in the pot and stir. Remove from heat and serve.
Dessert . . . think fancy brownies. Chocolate Hot Lava Cake. You can buy this stuff in a mix, often frozen/refrigerated. You make it just like you'd make pre-mixed brownie mix. But the magic is the middle of it stays all gooey and warm. You cook it in a muffin pan or a mini-bunt pan. Flip it over and serve with a little vanilla ice cream on the side.
For coffee with dessert, add about 3/4 of an ounce of Kahluah to the cup of coffee, top with whip cream, and then sprinkle with some chocolate jimmies or some coarse colored sugar (red & green during the Chrismas season)
After reading what you guys wrote I'm surprised any of you have kids. Did you just get your wives drunk and have your way with them while they slept?
