This is a tough question to put into words because I don’t think that there is a term for it. What food do you eat when you are not sure what you want and that you can eat multiple times without getting tired of it? Do you have a “standard” meal?
I personally can eat a 6 inch Subway Club on wheat with Sun Chips and a cookie along with a Dr. Pepper at any time day or night regardless of how I feel and regardless if I just had it yesterday. If I am at home, I can always fall back on Cambell’s clam chowder with a few croutons along with a salad with bacon bits regardless of circumstances.
Let me give you a few situations that might help people understand my question. What food do you like to eat: when you are hungry but are not sure for what, when you had a big lunch and don’t feel like having something big for dinner, when you are tired and don’t feel like cooking, when you woke up late- maybe too late for breakfast then all the sudden it is 11:00am and time for lunch, when you are driving to the lake or state park and you need to eat a little something before that won’t waste much time or get you too full, when you start to feel like you are coming down with something and you don’t feel like eating anything “challenging”? I am not necessarily talking about “comfort food” but I am sure that many people’s comfort food and “Standard, baseline, fallback food” are the same things.
