What does the Gita say about eating non-veg?

आयुःसत्त्वबलारोग्यसुखप्रीतिविवर्धनाः ।
रस्याः स्निग्धाः स्थिरा हृद्या आहाराः सात्त्विकप्रियाः ॥

āyuḥ-sattva-balārogya-sukha-prīti-vivardhanāḥ
rasyāḥ snigdhāḥ sthirā hṛdyā āhārāḥ sāttvika-priyāḥ

The kinds of food that increase life, energy, strength, health, comfort, and relish, which are savory, oleaginous, full of nutrition, and agreeable, are liked by the good.

यातयामं गतरसं पूति पर्युषितं च यत् ।
उच्छिष्टमपि चामेध्यं भोजनं तामसप्रियम् ॥

yāta-yāmaṃ gata-rasaṃ pūti paryuṣitaṃ ca yat
ucchiṣṭam api cāmedhyaṃ bhojanaṃ tāmasa-priyam

And the food that is cold, tasteless, stinking, stale, impure, and even leavings, is liked by the dark.

अहिंसा सत्यमक्रोधस्त्यागः शान्तिरपैशुनम् ।
दया भूतेष्वलोलुप्त्वं मार्दवं ह्रीरचापलम् ॥

ahiṃsā satyam akrodhas tyāgaḥ śāntir apaiśunam
dayā bhūteṣv aloluptvaṃ mārdavaṃ hrīr acāpalam

…non-violence, truthfulness, freedom from anger, renunciation, tranquility, freedom from backbiting, compassion for all beings, freedom from greed, gentleness, modesty, absence of vain activity…

पत्रं पुष्पं फलं तोयं यो मे भक्त्या प्रयच्छति ।
तदहं भक्त्युपहृतमश्नामि प्रयतात्मनः ॥

patraṃ puṣpaṃ phalaṃ toyaṃ yo me bhaktyā prayacchati
tad ahaṃ bhakty-upahṛtam aśnāmi prayatātmanaḥ

Whoever with devotion offers me leaf, flower, fruit, water, that, presented with devotion, I accept from him whose self is pure.
