Easy beginners recipe for that special meal:
Get some meat. Any sort of real meat will do, even sausages (but only from a good proper butchers). Perhaps not burgers, or mince. Chicken breasts & pork steaks are versatile and girls seem to like white meat more than red.
Chop the meat into bite sized chunks or strips (or buy it as stir fry). Add a bit of salt and pepper and cook it in a frying pan with a chopped onion and no more than a teasponful of cooking oil over a medium setting for 5 mins or so. When the meat is cooked through (chop a bit in half to test and it's cooked if there's no pink bits left) add a glass of wine to the pan, doesn't matter what colour. Boil it for minute or two. Remove from heat and stir in a bit of cream before serving.
If you want to be a bit more adventurous add a crushed garlic clove at the beginning or a generous spoonful of french or grainy mustard at the end, or both.
Serve with rice (Uncle Ben's Easy Cook will do - just follow the instructions on the packet) and a mixed green herby salad (parsley, baby spinach, rocket, watercress, coriander etc, comes ready mixed in a bag from the supermarket) and the rest of the bottle of wine.
Not too many ingredients, no critical timings - just dead quick, dead easy, never fails. The wine and cream sauce makes even the cheapest ingredients seem a bit special. If she's a veggie it also works with quorn steaks or with salmon or tuna steaks. If she doesn't even eat quorn - get rid, she's not worth the hassle!
