Wine can run from $2.00 to unGodly. The "Two Buck chuck" available at Trader Joes' actually scores pretty well. A lot more choice at eight to twelve dollars. The wife might go for $35.00 a few times a year. In California you can get most varieties of flavored Ethanol in most Supermarkets. I second the people who tout one pot meals. Instant rice has been a life-savor (pun intended) for me while camping. Consider cooking more than you need at supper time and heating the left-overs for breakfast. I did not like the risk of shell eggs or the litter of egg substitute and just carried freeze-dried eggs.

Chat with lots of people along the road, ask what local food they recommend, bemoan the pain of trying to cook it over a single tiny burner, and get invited to dinner.

One of my most memorable cycle touring meals was at a truck stop on Interstate 80 in estern Wyoming. Leaned my bike next to the front door, sat at the first open seat at the counter and ordered the biggest breakfast (for lunch) wolfed it down, paid, and went back to fighting the headwinds towards Nebraska. No one batted an eye, and I got quick service. Another was on the annual Palm Springs weekend trip of the Bicycle Club of Irvine.
I was scarfing down yet another plateload from the buffet when someone said. "Keep eationg like that and you may put on weight." Someone else said, "He rode his bike the 114 miles out her from Irvine yesterday." Dead silence.
