If you like simple meals you shouldn't really need recipes. Roast a chicken with some herbs. Cook a roast of beef in a a crockpot with some herbs. Saute fish filets in butter with lemon. Saute a sirloin steak in butter to brown it. Use a little dash of steak sauce on it while its cooking to spice it up. Some basic spices help: garlic powder, liquid smoke, paprika, ginger, thyme, basil, etc.

For vegetables, slice them, and saute them in a nonstick saucepan, in butter with a little oil. If you wish, add a small amount of heavy cream at the end and let it clot and absorb. You can sometimes add a little parmesan cheese to vegetables too.

I think I eat simply overall too, and those are the types of recipes I use. I just use a little imagination to vary the flavors and textures.

Good Luck!
