Method :

In a large pot sprayed with low calorie cooking spray cook the onions, chicken and bacon for about 5 minutes over a medium heat.
Add the rest of the veg and cover with stock ( make sure the stock is about 2 inches above the ingredients)
Add the oxo cubes, rosemary, salt and pepper, cover and bring to a boil, turn heat down to low to medium and remove the lid.
Let this cook for about an hour and a half.
Once cooked take about 1/4 of the veg out and put into a separate pot, add 200ml of warm water and blitz with a hand blender, the return the blended veg back to the stew. ( this will make it nice and thick).
