If I Do Invite The Eating Of Leftovers

Leftovers or once tasty treats
If there is anything used,
I would prefer to have near me...
Is a pair of old shoes,
I've taken off my tired feet.

Leftovers or once tasty treats,
I seldom eat.
Even if they happen to be delicious.
And If I do invite the eating of leftovers...
I initiated the cooking and generated the heat.
