I do a lot of cooking and healthy eating, and it's REALLY hard for me to get in enough sodium on a healthy diet. The easiest way for me to do it was salt tablets - you can buy them, or make them yourself. I buy a big bag of empty capsules and encapsulate Himalayan pink salt myself, then just take 2 with a meal. I also use electrolyte tablets if I'm going to work out. You might like this better than pedialyte, which has a lot of sugar and is pretty expensive.
