My Kids like this,
1 onion, chopped
3 or 4 carrots, chopped
3 or 4 potatoes, chopped
1 parsnip, chopped
chunk swede chopped
handful of barley
2tspns cumin,
pepper
1/2 pint veg stock.
Put it all in a pan and simmer for about 45 mins, keeping your eye on the amount of liquid. This will feed about 4 with some nice, crusty bread.
You could try onions, carrots, parsnips, garlic, couple of tins of mixed beans, veg stock, plenty seasoning. Simmer until veg are tender.
OR cook a bag of dry white beans. fry a couple of onions and a red pepper with some garlic until soft. Add 2 tins of tomatoes and some mediterranean herbs. Cook for a few minutes. Add cooked beans, simmer for about 10-15 minutes, then shake a generous amount of lemon juice over the stew and stir. Serve with crusty bread or rice.
