I use olive, canola, or coconut oil. I know WW doesn't consider coconut oil one of their 'healthy oils' but I do and I count it as such. Coconut oil is solid at room temperature and is so good when you use it to fry eggs or saute vegetables. It is also 1 point per tsp.
I'm usually good at all of the GHG with the exception of the oil. I have to try harder to make sure I get it in. The dairy I usually take care of with milk in my cereal in the morning and a yogurt for a snack.

saute vegetables!!! why didnt i think of that!!! >____<;

Or you can roast them in the oven with a little bit of olive oil/kosher salt/cracked pepper/maybe rosemary. I love to do this with butternut squash, brussels, carrots, and especially potatoes! SO GOOD.

i sauted them & added them to some pasta for lunch. Tasted soo good. Could taste the olive oil and mixed (salt free) herbs.. damn fine food!

We do that too! My favorites are potatoes and asparagus.
