Maybe it’s just me. I can’t eat large quantities of watery foods without feeling bloated, so there is no question I’d stop, because I’d feel sick. (Years ago, I was invited to dinner along with my parents at the home of their friends. For dessert, the hostess proudly served each guest an entire half pineapple shell that was overflowingly filled with the pineapple pieces and other fruit. I had to eat the whole damn thing because my Evil Glaring Mother would probably have locked me out of the house when we got home if I hadn’t. I had an upset stomach for about 3 days afterward.)
But if others could consume, say, a quart of grapes at a time … well, it still wouldn’t be terrible-terrible, compared to a lot of things. But I agree that it might be wise to eat carrots instead.
My wife just left on a weekend trip. Before she did, I peeked in the bag she brought home from Trader Joe’s: the usual snacks, including trail mix in small “individual serving” bags…
…and a new addition: a can of Maple Spiced Roasted Nuts. She says the sweet/salty/warmth is perfectly blended.
Along the same flavor profiles, dried seaweed is good. It has a lot of flavor without a lot of calories. You can find it sold in packages of small sheets that are good for snacking.
And it’s one of the few cereals that’s 100% Whole Wheat (except for the frosting). And I find that something crunchy really helps*.
Another crunchy snack: when I stop for gas, I always buy a couple of those small “sleeves” of nuts. Planter’s has some “Chili Lime” and “Heat Peanuts” that I love.
*I just realized that it’s like my doodling in church: having something (like audiobooks and snacking) going on “in the background” helps me focus on driving.
Well an appropriate conclusion to this thread is the cereal I happened to try on my last journey was indeed frosted mini wheats and they were great.
Not too unhealthy, they go down well but you can’t eat too much in one sitting and very cheap.
Sometimes they glop on a huge pile of condiments so I’ll have them leave everything off when driving. There’s also an inverse relationship between the volume of the condiments and the number of napkins they provide.
