This mod adds ham and beef sandwiches, along with mayonnaise. You can combine kelp, a sea pickle (yes I know they aren't edible in real life), and a bottle of mayonnaise in any combination with two bread and steak or pork. You can have a plain sandwich, a sandwich with just pickles and mayonnaise, a sandwich with everything, etc. The sandwiches are place-able and can be eaten like cakes.

Any plain sandwich gives two hunger points per slice, any sandwich with one ingredient added gives three hunger points per bite, any sandwich with two ingredients added gives four hunger points per bite, and any sandwich with all ingredients added gives six hunger points per slice.

Nqyte's Sandwiches Blocks

To craft the sandwiches, bread goes in the top middle and bottom middle slot, and steak/pork goes between them. To add ingredients, kelp and sea pickles go on either side of the steak/pork, and mayonnaise goes in any corner. To craft a bottle of mayonnaise, put an egg and a glass bottle in any combination on a crafting grid.
