We didn't do much store bought baby food with babies #2 & 3, and baby #1 only used it for about the first month he was eating solids. DD7 ate baby food when we were out because it was so much easier to keep a jar in the diaper bag, but never at home, and DD1 has refused it altogether.
What I started them on was soft veggies, mostly. Carrots, potato, sweet potato, squash, - cooked soft and mashed with a fork, they all make easy early baby foods. Ripe bananas and avocado work well too, and of course things like yogurt, unsweetened apple sauce, and oatmeal that are mushy/soft in their adult form. Once they were ready for a little more texture, I went to using a Happy Baby food grinder (you can pick one up for about $15, it is just a manual food grinder that comes in a carrying case) and just tossing a bit of our meals in to grind into baby mush. We follow all the basic rules about introducing one new ingredient at a time (and we're religious about it, because of a family history of serious food allergy), but by about 10mo all 3 of my kids were eating mostly what the rest of the family eats.
