Pasta Pre-cook
Before I leave home I cook any kind of pasta I think we may need, drain it and put it in a zip-lock bag in the fridge. When we are on the road I combine a packet of tuna with cold pasta, chopped vegetables and mayonnaise for a pasta salad. If I have cooked spaghetti or linguini, I will put it on our plates, zap it hot in the microwave and pour a microwaved small jar of sauce over the top. A sprinkle of Parmesan cheese and we are happy.
