Food sites on the Internet are a good source of ideas for spicing up your brown-bag lunch.
Here are some tips for creating better brown-bags from The Electronic Gourmet, www.globalgourmet.com:
Splurge. If you are brown-bagging to work, you are automatically saving money by not eating out. So, by all means, make your food more enticing than the local fast-food chain's. Make prosciutto, tomato and basil sandwiches, or pick up a roasted chicken from the deli and pack a portion for lunch.
Grilled thrills. Nothing adds more flavor than grilled foods. Add grilled veggies (onions, zucchini, eggplant) to your lunch. Bag them separately, then add to a normal sandwich. They're especially good with goat cheese.
Lunch pooling. Form a lunch pool at work with four other people. Each day of the week, one person makes lunch for all. It's easier to make five of the same lunches at once than to make five different ones every morning.
Condiment heaven. Explore new condiments on your sandwich, such as sun-dried tomato spread, horseradish, Chinese mustard, spreadable goat cheese and Caesar salad dressing.
