Take some chicken breast and chop it into little pieces.
You will also need some eggs and breadcrumbs.
Crack and beat the eggs into submission.
Afterwards, coat the pieces of chicken breast with the beaten eggs.
Put them into a box with the breadcrumbs. Shake the box for about 45 seconds.
Fry the resulting mess until the breadcrumbs start browning, then flip them over.
Voila, homemade, semi-healthy (at least, moreso than the crap at mcdonalds) chicken nuggets.
