my faves are
butternut squash, chop it and roast it first though, blitz it to make it super smooth and serve with parmesan crisps. Grate little piles of parmesan onto a baking tray and into a hot oven with them until the edges are golden, get them off the tray before they are cold or they will weld themselves to the tray fro all eternity
yellow split pea and ham...cook a smoked hough until the meat is falling off, start the soup with sweated celery and onions, add stock, pre soaked yellow split peas ( or red lentils at a pinch!) cook until th esplit peas are mush and then put the ham back in
Chicken Medicine soup....whole chicken or drumsticks, (you MUST have bones in it!!) Cover the chicken with water and poach with onion celery carrot, lots of parsley, couple of garlic cloves, lots of salt. Once the chicken is cooked, drain and keep the stock, take all the chicken off the bone/carcass, fridge the stick overnight and skim off the fat in the morning
Restart with fresh onions/celery/carrots but chopped really finely and sweat those, add the skimmed stock, plenty of S&P, more parsley, again finely chopped simmer gently, and add snapped spaghetti, drop in the chicken and once it's all piping hot serve....this is guaranteed to chase off all cold and flu germs!
