Lunches to pack that won't up my baggage allowance

I took microwave rice, lentils, couscous packs on holiday, to go with fresh salad/vegetables purchased locally. I also took some herb mixes to season things.

Stuffed Wraps work well with bags of salad. You could freeze the fillings so just have to tip in a frying pan to warm first, chicken or beef fajita, veg or even just tomato & cheese grillled like a pizza. Simple!

packets of couscous.there are lots of exciting flavoured ones.
do you have a favourite seasoning.cajun,jerk,five spice,italian.buy a few packets to put on veg or potatos for a bit of something different to go with lunch.
toastie bags.or just make toastie on the hob,grill when you there.

really easy to make flatbreads.3 spoons of yoghurt,3 spoon of flour.1 tblspn of oil.mix makes two delicious flatbreads to liven things up.
if they sell rice there.just mix through some frozen veg or other sladie bit you can find.ham.make egg fried rice.
omelete.
frittata.
lots of supermarket do packets of rady cooked grains now to.with some yummy flavours.they are really flat.

John west do lovely tuna pouches, all seasoned with Lemon or tomato. We always take them on holiday.

You're not allowed to take food products overseas

You can usually take packets of commercially prepared food in unopened original packaging to most countries. Some countries will not allow in any home-made food, opened packaging, or unlabelled packaging.

That said, I really wouldn't bother. There's always something to eat - be adventurous! Don't just go for the boring, safe options, have something different and unfamiliar every day. Save your baggage allowance for stuff you really need, or want, or souvenirs.

We tend to take mixes of spices and that sort of thing with us as you don't always want to buy whole tubs even when they are available. You could take some wraps and dry fry them with cheese and meat (salami/pepperoni/ham etc) or whatever (peppers, onion etc) between two wraps (turn when warmed through on one side) and then cut into wedges like pizza. Mine enjoy toast and poached egg when we are away which should hopefully be avaiable. Packets of noodles? Cup a soup or packet soup like chicken noodle)? Bread and jam for a change? You could also do some spicy potato wedges with melted cheese on though I've not always been able to find potatoes!

Tinned potatoes sliced up and fried with veg or whatever and added beaten egg to make a nice fritatta type thing?

If taking in hand luggage, don't take anything remotely paste like ( cheese, pastor etc) unless under 100ml or it will get confiscated and will need to go in a bag with your toiletries.

People take food on holiday?

This blows my mind. Going to forrin supermarkets is a holiday highlight, surely?
