If you are looking for a throw together lunch or quick dinner option, then you might want to give this recipe a go. By the time you cook the pasta, everything will be ready to assemble. And if you buy skinny pasta the cooking time will be even quicker!
To take this to work, you will want to cook the pasta at home, and throw it in a container to take to work. I would keep the lettuce separate while the pasta cools down to keep it from wilting. Everything else can be added to the pasta at home, or you could take the salmon or chickpeas still in their tins to add later.
Another alternative is to use baby spinach leaves and then some wilting is more acceptable than wilted lettuce.
You could eat this all separate as pictured or stir it together to combine the flavours. Either way, it is tasty and will be a quick and healthy lunch option.
