Expanding my cooking horizon...

I'm 21. I'm married. I need to know how to cook. I have the basics down, but I get tired of cooking the same stuff over and over. Here are the things I do know how to cook:

• Crock Pot Roast
• Spaghetti
• Baked pork chops
• Chicken casserole
• Crock Pot Chili

And that's about it. I know the basic stuff too, like hotdogs and burgers and all that, but I'd like to add more dishes that last a few days, don't have a million ingredients (I'm not Ina Garten, if you haven't noticed) and doesn't cost a lot to make. Soooo if you have any that you'd like to share, or links to posts about it, pleaseeee share!!
