I'm currently riding the TransAm (Eastbound). It's late in the season and I've had cool weather, so I've definitely wanted hot meals and morning coffee.
I started with my Solo Stove Light. I love this because it's light, I can fly with it, and I don't have to take or buy fuel (though alcohol fuel is an option). The problem was that campgrounds and forest rangers asked me to put it out, even when in a fire pit, due to the high fire hazard especially between Oregon and Colorado. Solo stoves are supposed to be allowed. But I was chastised too many nights. It also takes a good bit of time to gather the wood, tend the flame, wait for sufficient heat, wait for the boil, etc. It was fun the first week. Then as the days grew shorter, I found it a stressful rush to need over an hour to cook dinner and breakfast.
So I mailed that home and am now using a small handheld immersion heater with my Solo Pot 900. It's much faster after a long day on the road. I mostly stay at established campgrounds, city parks, churches, or hostels so I borrow power from a picnic shelter, a bath house, or an RV site. I started selecting simpler meals, mostly things that just require boiling water (still plenty of options). A few times I put it directly in a can of stew. On the rare occasion that I didn't have access to power for the 10 minutes to boil the water, I just ate a room-temperature meal instead. Honestly, I'm pretty tired and ravenously hungry at the end of every day, so even as a foodie, it's not such a big deal if I miss a warm meal occasionally. But if your main plan is primitive camping, that wouldn't work unless you stop and prepare your meal at a convenience store or city park along the route.
The rest of my kitchen kit: a titanium spork, a collapsing silicon bowl with lid/plate, a polypro cup, a pocket knife, and a mini can opener.
I also had a skillet with removable handle. I didn't use it. The solo pot is sufficient. So I mailed that home too (with a bag of fascinating Montana rocks that a kind camping neighbor gifted to me...yikes!).
For cleanup I started carrying a Mr. Clean Magic Eraser. It works to remove grease (always a problem with bullion cubes) & flame char (if you care) on the stainless steel, even with cold water. It drys quickly. They're "squish-able" and lighter weight than a washcloth.
