I do a fair amount of cooking - I'm a big eater.
I've never had any formal training, just lots of basic stuff with a little creativity thrown in. I'm a big meat eater - like lots of beef, some pork, and a little chicken here and there. I'm big on seasonings, herbs, sauces, hot peppers, condiments, etc. Not big on sugary or sweet stuff. I have to reduce the amount of spices and seasonings I put in by at least half if I'm cooking for others.
Barbecue / grilling, roasts, Tex-Mex, and Italian style dishes are favorites. Grill steaks and burgers at least once a week. Barbecue / slow smoke meats like pulled pork and brisket 1-2 times a month on the weekend because it takes far more time and attention than grilling.
