Poison Control Hotline may sound offensive. I wonder if any other kind of nuts can be a problem? Certainly there may well be some people who like to spend time on their PCs who might qualify as potential candidates.
I would never include peanuts because I’ve heard so many people are allergic to them and it can put a real damper on any kind of celebration if one of the guests needs to be spirited away to a hospital in an amublance. But there are many, many others to chose from. My favorite kinds of nuts include cashews, almonds, pecans, walnuts and sunflower seeds. Trail mix is always healthy, tasty and almost never requires refrigeration. You can Google “trail mix” or “how to make trail mix”. I like a big dish full of nuts and raisins. What are some things we cam make ahead of time, but don’t need either refrigeration in the interim, and don’t need heating before the meal, either? We can store the dishes inside, but we won’t have access to a refrigerator.
I’m planning a potluck where most of us will arrive at 12:00, but the food won’t be served until 6 to 7 hours later.
