1. It calls for 2 tsp salt. Holy high cholesterol Batman! I use 1/2 tsp salt and it tastes fine (remember cheese already has a higher sodium content)
2. I substitute spinach, not really a collard greens fan : /
3. Still can't really have spicy stuff yet, so just an fyi, it tastes fantastick w/out the red pepper flakes.
That's all. Enjoy the yummy Italian dinner :)
