Backpacking....

I carry a Trangia 28 alcohol stove, which includes a pot and pan, burner, simmer ring, windscreen, and pot lifter in a very compact, clean, and convenient package.

I also carry a titanium mug and a spoon.

Everything I "cook" is prepared by adding boiling water. Lunch doesn't even get cooked.

I use about 3 oz of alcohol (stove fuel) per day.

Breakfast: Instant oatmeal and a granola bar. Tea.

Lunch: Foil packet of tuna or chicken with prepared condiment mix (relish, mayo, mustard) to make chicken or tuna salad. Water or water with Emergen-C mix.

Dinner: Various flavors of Ramen noodles. Maybe add some leftover meat from lunch. Granola bar for dessert. Tea or coffee.

That's it. A full day's menu fits easily into a 1 quart freezer ziplock bag, which gradually becomes the trash bag for that day.

You'll find lots of compact, lightweight menus at:
