A local food truck in Austin, Texas sells a sausage named "Predator and Prey." Well, it used to. It consisted of rabbit, snake, and filler meat. Supposedly. I never tried it.
Point is that is a damn good sausage recipe for the game, since snake is (i think?) not used in any sausages and rabbit rarely is.
Besides that I'd like a nice bulk, low/mid FEP sausage similar to the gap that piglets fills. Maybe a red-meat based kielbasa? An example: Killer Kielbasa, requiring 2 of any dangerous animal meat (can aggro, or maybe simply red meat), plus a spice. Maybe even onion, as a mince (though obviously its just an onion in game.)
I'd also like to suggest the adding of a pepper crop, something like jalapenos, and then adding a jalapeno and cheese sausage. Could be beef 2x, pepper 1x, any cheese slice 1x. It could be a nice mid/high tier sausage, considering the cheese.
If you were to add tomatos as well, you would open yourself up like minimum 10 new recipes that could be banging. pico-de-galo (pepper, onion, tomato), tomato soup, sandwiches as a whole category, plus add a freaking pasta AND BAM man you've got another dozen dishes.
Let's be real, its a cooking simulator in addition to whatever else the game is. Let me chef it up, please. I love cooking. Also add garlic stuffed olives and pepper stuffed olives.
