easy veg with almond sauce

I've been living like a student for the past two weeks, quite a change from my usual routine as mother of 2. I've been working like crazy and needed quick and grounding food. And made this almond sauce with pasta twice (= 4 meals)! Very nice with whole grain spirelli or spaghetti. Might also go well with rice or other grain.
This is enough for about 2 people.

1 tsp oil
1 small onion
1 punnet mushrooms, or a handful of carrots, a small head of cauliflower or broccoli, some beans...
2 tsp mixed dried herbs
salt, pepper
2 tbsp almond butter (the unsalted variety made from roasted almonds in their skins)

Soften the onion in the oil. Saute the vegetable of choice for a while.
If using mushrooms, add the rest of the ingredients. Mix the almond butter with a cup of warm water, add to the veg, heat through, add more water if you want more sauce, serve.
If using other veg, add some water and the seasonings, cover and cook till veg is soft. Mix the almond butter with a little warm water and stir into the pan.
