Not just vegetarian go for 100% satvik food as well. What lord thyself consumes… See Gita 9.26 “patram — a leaf; puṣpam — a flower; phalam — a fruit; toyam — water; yaḥ — whoever; me — unto Me; bhaktyā — with devotion; prayacchati — offers; tat — that; aham — I; bhakti-upahṛtam — offered in devotion; aśnāmi — accept; prayata-ātmanaḥ — from one in pure consciousness.” It does not require to kill anyone, “not even the plant” if one consumes fruits, leaves and flowers that has naturally fallen on its own. Remember to plant the seed and not to harm the same while consuming satvik food.
