Some Assembly Required is a Farmer's Delight and Create add-on that allows players to create custom sandwiches.
To get started, create some bread slices using Farmer's Delight's cutting board, or make a burger bun. Then, place down a Sandwiching Station, place a bread slice or bun on top, and start adding ingredients. In addition to food, potions can also be added. Once your sandwich is finished, you can pick it up by breaking it. Sandwiches can be placed down anywhere in your world by shift-right-clicking.
A sandwich restores the same amount of hunger and saturation as it's ingredients. However, if it contains at least 2 unique ingredients (excluding bread and potions), it will additionally grant a Comfort buff if it's a sandwich, or a Nourishment buff if it's a burger. The length of this effect increases with the number of unique ingredients.
If doing things automatically is more your style, you can automate the production of sandwiches using Create's deployers. Furthermore, spouts can add fluids such as potions, honey or chocolate to your sandwiches. A full list of compatible fluids can be found in JEI.
