Curried vegetable stew recipe

I think I'm just posting this for myself, so that when I come up with something that works, I'll remember it...

2 carrots, sliced thinly
1-2 potatoes, diced
1 bunch bok choy, chopped
1 head broccoli, chopped
1 green pepper
3 sticks celery
1 onion, chopped
2 large cloves garlic, minced
16 oz diced tomatoes
vegetable oil
curry powder (or mix turmeric, cumin, coriander, cinnamon, allspice nutmeg, fenugreek, ginger, red pepper, black pepper, to taste)
mustard seeds
cumin seeds
cilantro, chopped

Heat oil with mustard seeds.
Add onions and garlic when seeds start to pop, cook till soft.
Add potatoes and carrots, curry powder/spices and cumin seeds, and cook covered for 10 or so minutes until softening.
Add celery, broccoli, green pepper and some more vegetable oil.
Cook for a few minutes and once oil is mostly gone add diced tomatoes.
Cook until soft. If it appears slightly dry and vegetables appear undercooked, add some water.
Serve with cilantro and rice.
