I would start with a simple cold starter, then you can have it made before hand, smoked salmon or melon with parma ham.
Then how about a pot roasted beef( portugese style), place a joint a beef (brisket or silverside whatever) in a large casserole dish, add 1/2 bottle of wine, tin of tomatoes, an onion, couple of cloves of garlic, 1 tsp paprikaa red pepper. Place in the oven on a low heat or slow cooker if you have one, cook for about 6 hours. when you want to serve it, take it from the juice, carve, puree the juice (instant gravy, no need to thicken)
Serve with roast potatoes with a green veg
Again I would serve a cold dessert, less messing, you can get very good quality desserts in the supermarkets if you don't want to make yourself, probably choclate and then a good chocolate.
Hope this helps
