Whatever thou doest, whatever thou eatest, whatever thou offerest in sacrifice, whatever thou givest, whatever thou practisest as austerity, O Arjuna, do it as an offering unto Me.

Whatever you do, whatever you eat, whatever you offer in sacrifice, whatever you give, whatever austerity you practise, son of Kunti, do it as an offering to me.

Krishna extends the idea of offering to the whole of life. Whatever Arjuna does, eats, offers in sacrifice, gives or undertakes as austerity, he should do as an offering to Krishna. Daily acts, not only formal rituals, become worship. The verse turns the Gita's teaching on action without attachment into a devotional form: actions are freed from selfish motive because they are dedicated to God. It is a practical way of living the earlier instruction to remember Krishna at all times.
