Don, thanks for the link to the receipe. Here are the ingredients for the SB version:
1 tsp extra-virgin olive oil
1 clove garlic, diced
1 pkg (6 oz) portobello mushroom caps
12 oz mozzarella cheese, sliced or shredded
10 fresh basil leaves
2 fresh tomatoes, sliced, roasted or grilled
Pinch freshly ground black pepper
Pinch salt
Oregano leaves (optional)

This serves 2 at 14 g carbs per serving.
Atkins says 5.5 per serving. I can't see what the big difference would be unless it's the size of serving. Do you? Plus, all the ingredients listed in the SB recipe are O.K. for Phase I. Don't get it. But, just in case, I'll wait for Phase II. Both recipes sound good.

Loon, thanks for the encouragement. I made it thru second day without too much griping. Tonight I'm going to the store to get all the "good" low carb stuff. The last two days I've just been searching the fridge for what I could have. Now I'll be better prepared with a bigger selection of the right foods. I am a little concerned about going to the show. Like you, I love my popcorn. It's half the fun!! I guess I'll just take some nuts. But for the same calories, nuts go so fast. Popcorn takes longer to eat. I do know that in Phase II I can have popcorn. That's only 2 weeks. :)
