Cor! You are missing out. :wink:
Olives. Pick them up between thumb and forefinger from pot/jar/tin/packet, place in mouth and chew. The advantage of those deli counters is that they will let you try a bit of anything to see if you like it. I'm not so keen on the small, dark purple ones but love the big, fat, garlic stuffed green ones. They all have names but I can never remember them.
As for a sweet potato, peel it (or not, as you desire, personally I don't like the skin on a sweet potato as much as I liked the skin on an ordianary potato) and use it as you would any other potato. Cut into big chunks and throw them next to a joint of meat roasting in the oven, or boil, mash, chip, wedge, anything really.
I've got laods of really easy recipies for veggies because although I can cook, I like it quick and simple. Let me know if you want any.
