If you don't want to do turkey and all the trimmings, is it that it's too much faff for one, or you don't actually like turkey?
If you LIKE turkey, a small breast joint can be easily done and would have some leftovers but not so much you can't use it up in a couple of days (1 sandwiches meal, 1 leftovers curry/reheated in gravy/pie) or freeze leftovers for using at a later time (it freezes really well). And the sides can be baby potatoes roasted (leave skins on, but halve the spuds, toss in olive oil, salt/pepper, dried rosemary and garlic granules in a plastic tub/Ziploc bag the day before, then just toss into a roasting dish for 45-60 minutes), 1 favourite veg dish (lots can be pre-prepared eg cauliflower cheese can be made and frozen to throw into the oven to heat up, or as simple as nice frozen peas boiled up), and gravy made with the turkey juices and some bisto powder or similar. So quite minimal fuss but still lovely.
When I am alone, I love to do things like lamb shanks roasted slowly, with some mediteranean veggies and baby roast potatoes, or sometimes roasted root veg and creamy mash.
Sometimes it is very simple - cured meats, cheese, pate, nice crackers (I got some lovely sourdough ones last year, really moreish), olives etc. Just laid on the table to nibble as I sip something lovely (Lidl do their prosecco in half bottles, for example, or I might open a bottle of wine and put the cork back in after a glass or 2 to drink over the next few days, sometimes its as simple as really nice lemonade) and read my good book or watch good movies.
If I'm going to be out and about, and need something warming when I get in, I make a pot of soup. It can last a few days, extra can be frozen, but it is great to have to just heat up and re-warm after an outdoor adventure. I particularly like:
- chunky mushroom (I put a dollop of crème fraiche in the bottom of the bowl, and snip some chives over the top to make it special);
- rustic tomato (gently fry a chopped onion, add a tin of Campbell's tomato soup and a tin of chopped tomatoes, measure the milk and water (50/50 mix) to add in the soup tin, but swirl it around both tins before adding to the pot to get as much tomato out of both, season with dried herbs (oregano or basil or thyme) and heat through);
- cauliflower (really tasty!); or
- a hearty chicken and veg soup.
