SQL & PL/SQL

If I have a table as follows

Table A(
meal varchar2(32),
beverage varchar2(32),
desert varchar2(32));

and the table contains a row

meal beverage desert
-------------------------------------------------------
pork chops iced tea apple crisp


Is there a way in pl/sql to retrieve the column names along with the values. I have an object type
DATA_DEFINITION_T AS OBJECT (
"FIELD_NAME" VARCHAR2(32),
"FIELD_VALUE" VARCHAR2(32)

I need to store the column name in field_name and the column value in field_value.

So the result would be:

FIELD_NAME = meal
FIELD_VALUE = pork_chops

FIELD_NAME = beverage
FIELD_VALUE = iced tea

FIELD_NAME = desert
FIELD_VALUE = apple crisp

Thanks in advance.
