Usually we fry the mixed veggies separately for the traditional vegetable stew, but this is the quick and easy version i usually make with left over boiled veggies .
( when i boil the veggies for my Russian Salad , i reserve some for my quick stew.)

INGREDIENTS:

1 big bowlful of diced and boiled ..
Potatoes , Carrots, greenpeas, french Beans ;

2 Big Onions finely sliced

grind to a paste: ( or please refer to my Red Hot Bomb Paste ….. 1 big tablspn. )

4 cloves garlic , 2 dry red chillies ( the Kashmiri ones known as rasampatti )
1tblspn. cummin seeds .

METHOD:
Take a pan and fry 2 big onions in 2 tablespn. refined oil till golden brown.
Add ground masala paste to onion and cook 5 minutes adding a little water if it sticks to botton of pan.

Add the bowl of diced and boiled veggies and fold in well , please see to it that u dont mash up the vegetables while mixing .
Add tomatoe ketchup or hot and sweet maggie tomato sauce.
Add 1 tsp. vinegar (optional) 1 tsp. worcestershire sauce and cook 5 to 10 minutes longer.

If you need a little gravy just add half cup water and cook till the stew absorbs the water and is almost dry.

Serve as a separate vegetable dish or as an accompaniment to Mutton / Chicken / Fish cutlets , chops or patties.
