Soups really can have almost anything in that you like but since you want to pack in as much nutrition as possible try to include things that pack a protein punch as well as vegs eg-
Tomato, mixed beans and ground beef;
Tomato, cumin and red lentil;
Make ratatouille (google) but thin down with veg stock/tomato juice and add cooked rice or pasta;
Cook down whatever veg you have with ginger and garlic say onion, peppers, mushrooms and sweetcorn and add half and half chicken stock and chinese-y ready-made sauce like teriyaki/ hoisin for and easy oriental style soup- finish with some noodles cooked into it in the last 5 mins and cubed cooked chicken and you have a very satisfying soup indeed;
my personal fav soup of all-
diced swede, onion , celery, leek, carrot and minced garlic sweated down: add diced chicken, cook out and top up with chicken stock and sweetcorn, cook out and eat with crusty bread.
Butternut and bacon finished with a bit of cream and spoon of green pesto
Indian spiced vegetable with chickpeas
-diced mixed veg of your choice but include some fresh red chilli, ginger, medium spice mix,once fried all together add spoonful of mango chutney , veg stock and cook out finish with greek yoghurt, mint and coriander leaf
Thai red chicken:
diced onion, red pepper, cauliflower, carrot, celery, leek (plus any small amounts veggie leftovers in fridge) diced chicken ,sweat with red thai curry paste, salt and pepper, add spoonful brown or white sugar and cook out 5 mins, add coconut milk, chix stock and milk and cook until veg tender and chix cooked through, blitz semi smooth and serve with fresh coriander, prawn crackers, and sweet chilli sauce.
