I use these for peanut butter because I only eat all natural pb. One of the big pb brands used to sell single serving pb tubs they still might and Jif has single serve pb cups.
They work pretty well. you should stil place the filled tubes in a large plastic baggie. They can leak.

instead of the yucky instant ramen, have some MRE's (Meals Ready to Eat emergency food) handy. Some even have a built in heater for the food. Add water to the food and add water to the heater and it goes.

Okay so they a bit more expensive.
