As for a sweet treat, I heart those chocolate peanut butter cups (and chocolate peanut butter pretzels) from Trader Joe's, but in an effort to curb the calories, I think this Splenda-sweetened recipe might make a great, lower-fat alternative: Peanut Butter Chocolate Cheesecake Cups.
FYI: Have any of you read The Cuckoo's Calling by J.K. Rowling? That's our book of the month and so far it seems to be inspiring a lot of "meh" attitudes from the book club crew. It's too bad - I really wanted to love it, but had a pretty hard time getting into it. We're thinking about reading "The Fault in Our Stars" next, so apparently I'll need to get some tissues handy as I've heard it's a tear-jerker.
Anyhoo, if you have any insight on next books to read or yummy, low-cal appetizers to make, let me know!
