The food is one of dad's absolute favourite things to complain about. He makes a big fuss over being vegetarian, talking about it to everyone (and no judgement, he brought me up vegetarian and I'm vegan now) but he does eat fish so is really pesticarian. And last week he told a carer he does eat chicken now and then. I've never known him to eat chicken or any meat; I think it's probably been 40 years and he was vegetarian at school at one point, and had a vegetarian ration book in WW2!
At supported living he refused to make anything himself in his well appointed kitchen and then complained about the food in the restaurant, saying the people there were using meat gravy on everything (they weren't). Then when they banned him from the restaurant, I got meals on wheels in. I chose his menu every two weeks, and he loved it apparently. I chose a balance of light dinners like quiche and salad with sponge and custard, or a vegetarian curry with rice and naan with yoghurt for dessert.
Fast forward to the residential home. It's small so can't be too fancy and they offer a choice but of course dad often forgets what he's picked so it's always a surprise and not usually a good one.
He became very suspicious of anything looking like meat, like a vegetable lasagne. So they have been sticking to things which are obviously vegetable based. The home buy in tins of soup and for dad and the other vegetarian lady they sometimes buy ready meals but dad imagines it's a big kitchen where they are turning out enormous amounts of food and 'topping up the soup with meat stock'. He can tell apparently. In reality the home are heating up half a can of Heinz vegetable soup in the microwave.
The manager told me they have served more exotic fare but it doesn't get eaten so it's very much sausages and mash, fish with potatoes and vegetables, cottage pie maybe and so on. They tried putting more veg in, mixing it with rice to look nice but every resident picked out the peas and sweetcorn and left them on the plate! I think you'd be hard pressed to catch a baked sweet potato with feta there.
