I agree with thisisnotatest, your have to move away from prepackaged and processed foods.
My rule is I don't buy any box or package at the grocery store that has ingredients on the label that I can't pronounce. I'm a clean-eater, meaning I eat only natural unprocessed foods. I know, it sounds boring but it's worked well and I've lost quite a bit of weight.
I know you already found some alternatives, my favorite are the recipes in the Eat-Clean diet books. Try Tosca Reno's Eat Clean Cookbook. I love the ideas of ways to eliminate salt and replace it with agave nectar or maple syrup. There are a lot of other options, you just need to do your research and of course eliminate the salty, pre-made and pre-packaged foods!
