From the dept. of unanswerable questions dept: 5 things you've eaten that you think everyone should eat before they die. Found this via Gluten Free Girl and I agree with her that the only way to answer questions like this is to go with the first thoughts = best thoughts approach. So my answers are no definitive, in that if tried again tomorrow, I'd probably come up with 5 (or 10) completely different things.
First thoughts:
fior de latte in Tuscany
fresh-picked tomatoes from your garden
roast chicken at Bouchon, Las Vegas
gelato di riso
bread you've made, fresh from the oven
Second thoughts:
NYC pizza
really fresh sushi
tomato jam
Texas 'cue (brisket!)
chocolate cake at Magnolia Grill, Durham, NC

Fish you've caught.
Vegetables you've grown.
Berries found in the wild.
Kambing Guleng (lamb, I think) cooked over a fire in Indonesia and served with a sweet-soy and pepper sauce.
A perfect piece of bush-ripened pineapple.
1, 2 and 3: yes. 4 and 5: not yet.
