What is the present progressive tense of eat?

That would have to be, "Eating" boss. There isn't any other way to say it.

What did you eat? Past

What have you ate?? Past

What are you going to eat? Future

What are you eating? Present

I am sorry, there are several mistakes in the answers supplied above.

There are two types of Present:

The Present Simple: I eat, you eat, he/she/it eats, we/you/they eat.

The Present Continuous: I am eating, you are eating, he/she/it is eating, we/you/they are eating.
