1. Have you ever had too much of a good thing, a food that you once loved but because you ate it too much it now gives you the willies just to look at it? If so, write a little story about how that happened. If not, write an imaginative tale what might happen if you ate too much of your favorite food.
Encourage students to be creative here, but not gross. Discourage them from copying Chocolate Fever by asking them to place their stories in their own hometowns, with their own families and friends and teachers, like Robert KimmelSmith seems to do in Chocolate Fever. When they're finished, encourage them to read them aloud in front of the class, and, for fun, keep track of all the different foods that they write about.

2. Take a poll of people's favorite and least favorite foods - your friends, your parents, your teacher. Make a chart where you keep track of the different things people like to eat.  After you've compiled all kinds of different food items, look for patterns and draw conclusions - what are the foods people seem to like the most; what do those foods have in common; are they salty, sweet? Are there any items you have never heard of? Pay attention to how many people's favorite foods are junk foods! 
Students should do this assignment over a few days, taking their work home and asking friends and families. Ask them to make a formal chart: to make a mark in the chart every time someone lists favorites like pizza or hot dogs, but also to add anew food (like Korean kimchi) to the chart when someone mentions it. Find out which kinds of foods were the most popular and maybe have a party, later in the year, where you eat those foods. Also, find out what some of the strangest foods were, and do a lesson where you tell the students a little bit about the culture from which they came. Discussing the diverse cultures from which great food comes will tie in nicely with the theme in Chocolate Fever about treating those different from us well and with respect.

3. Now choose one of those items and promise yourself to try it. Ask your parents if they'll buy this food from the supermarket, cook it for dinner, or take you out to try it at a restaurant. Be creative. Suggest to your school cafeteria that they try and make it, or maybe they already do!
