What kosher food should I pack for a one-week trip? I won't have access to a fridge; and no kosher food will be available at my destination.
The only food idea I can think of is tuna. That would get very boring. I need more variety.
(If you want hot food, then instead see the second half of the linked post. Some things listed there are easy, like instant soup-in-a-cup.)
If you're fine with cold food, then here are some ideas:
Bread: Pita bread or matzah are dense and compact. Another possibility: take along a bread machine - you can buy flour, yeast, etc., anywhere. (Alex has done this on a trip with his family.)
Fish: Canned tuna or salmon. Vacuum-packed tuna without the water. Canned herring in paprika sauce. (Delicious. Try it.) Canned sardines in mustard sauce (but the room and your breath will smell very bad). Canned herring in mustard sauce. Canned "tuna salad" in onions and tomato sauce. Fully cooked and ready to eat (or ready to heat) vacuum-packed salmon or tuna fillets.
Miscellaneous: Vegemite. (Spread an extremely thin layer on bread.) Canned baked beans. Peanut butter. (You can get by for a while eating nothing but peanut butter. When you're hungry, spoon some into a bowl and "enjoy".) Kraft cinnamon-raisin-granola peanut butter. Jam. Chocolate spread. Nutella!
Cereal: Your favorite kind. Granola travels well: it's very dense. Add milk or water. Also add some juicy raisins or other dried fruit if you want.
Milk: Powdered, evaporated, or condensed milk. Or aseptic-packed milk (like Parmalat, which has a hechsher in the US). Or aseptic-packed soy milk, almond milk, or flax milk. Try one of these milks at home; see if you like it. Even if you don't like it plain, you might tolerate it in cereal. After leaving soy milk unrefrigerated, unforgettableid has found that it doesn't go sour for some time: maybe a couple of days or more. Sniff carefully. If it's cool but above freezing, storing it just outside a window might work.
Water: Bring a big water bottle. Make sure that the manufacturer claims it's freezer-safe. Fill it up halfway with water, then freeze it the night before you travel.
Vegetables: Enjoy as many salads as you want. Though lettuce goes bad soon, bell peppers and other veggies are great.
Fruit: Most fruits aside from berries will last you a week. This includes avocados, which are great for long trips.
Oils, vinegars, spice, etc: Lots of shelf-stable foods.
Snacks: Unsalted pretzels. Granola bars. Chips and (individually packaged) salsa. Single-serve packages of apple sauce.
If you bring nuts or chips, repack them into single-serving plastic sandwich bags before you travel. These foods are very calorie-dense. If you eat them straight out of the original package, it can take immense self-control not to eat 500 Calories' worth in one sitting.
Meals: Shelf-stable, self-heating, packaged meals such as LaBriute brand.
Have a good trip!
