'RHONJ' star Teresa Giudice: I'm Cookin' Now!!!

'RHONJ' star Teresa Giudice is all business and gives very little away for free.

Our photog got her outside The London in NYC Tuesday and asked the most basic of questions ... what she ate on her first night of freedom.

We know this much ... the recipe's in her new "Skinny Italian" cookbook.

Teresa and husband Joe are still hustling to pay the rest of the restitution since Joe is headed off to prison soon.
