God had already said at some point "Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds", so He went with that.
For the sake of not procrastinating, then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food. Except the ones I don't want you to eat. And if you eat of each other, let it be healing.” And it was so.
Some adjustment to the Garden of Eden happened to carry that out. God chose to add plants that produced things like meat but without the ethical concerns: fruits, seeds, shed-bark, and all manner of things. The plants that were edible without any problems were replicated into the beginnings of farming. The plants that God had forbidden eating (mostly poisons, the Knowledge of Good and Evil, and a few other...experiments dissonant with the planned order of the world) were fenced off with a great faintly-shimmering dome. Cherubim with flaming swords that could face every which way were set to guard it, just to be sure.
And just in case people tried anything messy about unhinging jaws and carnivorous instincts, something about 'soft vore' and 'anti-cannibalism' was put in place through biological details. Stretchiness, nonharmful consumption, endosymbiosis, photosynthesis, bodily regeneration, and ejection, just to be sure. People would probably figure out self-distention eventually, whether by overeating or trying to shove something in their jaws. If they tried to eat or poison each other anyway they'd just recover shortly, or heal damaged sections in the attempt, or be able to take them in whole and spit them out later. And swallowing reproductive material would be a harmless good time all around. Bit of a hack job, but potentially funny and a good outlet for preventing use of force from getting dicey.
God blessed all His peoples and said to them, “Be fruitful and increase in number; fill the earth and subdue it." That said, new methodology probably had to be put in. God looked awkwardly at Lilith, who was just kind of over there outside in the nothingness-waters and planets outside the Garden, eating fruit with the rebellious angels. Lilith and the betrayer angels had discovered rudeness and sin, but God had allowed them to go bother in the hard-to-reach far sky, so as to not ruin His work. Maybe clearer instructions would help His peoples.
A few angels with curvaceous aesthetics modeling and a few female animals He had anthropomorphized were innocuous. But that was all the more reason to ensure they were on the same page. God told His angels the golem-making words, of how to craft dusty soil into lively matter and draw from the treasury of Guf to grant them the breath of life, and the knowledge to raise them. And God told His furries and scalies and so on the means to hold life within themselves as wombs or shell it out as eggs, and the intricacies of reproduction as the flowers did, and the knowledge to raise them. Adam and Steve got to sit this one out, but the angels would bring it up when the sons of God felt ready for child-rearing.
God saw all that he had made, and it was very good. And there was evening, and there was morning—the sixth day. God had His angels teach the anthros the great plan for tools and clothing, and Adam and Steve teach them various parts of living humanly, but made it clear such things were optional. The masculine form could easily be displayed if there was no reason to hide or protect it beyond its own strength, and His sons were a beautiful exhibit.
Thus the heavens and the earth were completed in all their vast array. By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done. And for a time, there was happiness in God's domain.
