Okay, so I have a potluck tomorrow night (finger foods) to bring to the reception after my daughter's confirmation.....and....I need to bring a main dish, and salad or desert to our homeschooling meeting on Monday! UGH!!! Please give me any suggestions that you can. I am 2 weeks and 4 days post-op!!! pureed/soft solids. Thanks in advance, Amy
