Easy Cauliflower Curry

I know I mention Trader Joe's products a lot but they're pretty good and allow me shortcuts that don't short change taste. I used their Thai Red curry cooking sauce for this dish and it came together fast and yummy.

1 head cauliflower, chopped in large pieces
1 medium onion in large chunks
some olive oil
1 bottle TJ's Ref baby spinach
handful of chopped fresh herbs. ( I used basil, parsley, oregano and thyme) but this is totally optional I had just pruned my herbs so I threw them in the curry!
Cooked brown rice

In large lidded skillet brown the onion and cauliflower for about 5-8 minutes so you get all the pieces a little brown. Add the sauce and cover-simmer for 20 minutes. Add the spinach, stir, and cover again for five minutes or so--long enough to wilt the spinach. Serve over brown rice. I also added some steamed asparagus to the bowl, but many other veggies would go just as well.
