hopeless

I just came back from the supermarket...and i'm really clueless what are the types of vegetables - its name and how it looks like! I was trying very hard to figure out if this......ehh......or this looks more like broccoli.

I also bought a pack of muddy purplish longish stuff which i thought was red potatoes...and i came home and realized it's yam!

I know my sis Sandra - who loves food & the supermarket - is going to strangle me!!! ;p
