He can summon Cans of beer, so clearly aluminum can be summoned/ Summon a ton of chicken wire, create a coop, and catch a few alive. selectively breed for a few generations to domesticate into more mild chickens, and he's sitting on a stable supply of both chicken and eggs. There is a reason Chicken is the cheapest meat IRL after all, and the fact they produce the side produce of eggs, opening up all sorts of dishes, is just a bonus.

Pasta Dough means Italian Pasta Dishes, with slight tweaking, Asian Noodles, etc.
