Your little guy can eat pretty much whatever you do. My daughter was a late bloomer as far as getting her teeth. I just made sure that everything I gave her was small enough that if she did swallow it whole, she wouldn't choke. Obviously, avoid things that are hard to chew like steak or roast, but everything else is pretty much fair game. If he doesn't want to chew, it may very well be because he's getting his molars.
As far as recipes go, check out www.kraftfoods.com. They recipes are super easy and the ingredients aren't anything strange. I also recommend any of the Taste of Home Best of Country Cooking recipe books. Those are what gave me my start in cooking. I'm not the best cook, but I can follow a recipe pretty well! Also Campell's website and Stove Top's website have some really simple and easy recipes. Once you get the basics, it's easy to expand on your knowledge.
Oh, and my dd LOVES casseroles. It seems like everything in it gets mushy enough that she can chew it whether she's teething or not. Trust me, I have a VERY picky eater! She'll eat just about anything....just when SHE wants too! Good luck and Happy cooking!
