Rick, ya don't know what you are missing!Onions, leeks, garlic, chives, shallots...a whole spectrum of good flavours that add to the total delicious-ity of food...
My dad would agree with you tho...he was a strict meat and potatoes man, no spices, no condiments except salt pepper and ketchup.And none of this fresh vegetable crap either--canned peas yessir!
My mom would occasionally try to sneak some onions/garlic etc into the roast beef, but Dad caught it every time...
