my initial idea was:
a picnic basket which can store food. can place it down, crouch + right click to open then right click with an empty hand to take an item. when you pick up the basket and have it in your inventory, baubles slot, or curios slot, it would auto feed depending on your saturation, hunger, health and available food in the basket. players would be able to tweak these settings e.g. "eat as soon as i lose any hunger" or "only eat when i'm down by 2 hearts" or "only eat right before i stop being able to sprint". i imagine there would be two sliders, a health slider and a hunger slider that lets you set the parameters of when it autofeeds you.
this could be expanded by adding more types of baskets or lunchboxes that have custom properties. for example, let's assume there's a lunchbox that is made of end stone and enderpearls. each time this box feeds you, all hostile entities in an undecided radius around you gain the "glowing" effect. this is a throwout idea so don't criticise me too much on this haha.
as i type i realise i'm drifting away from the initial idea, so i suppose a "lunchbox mod" would be more appropriate - similar to the lunchbags & lunchboxes in the slice of life mod but more thought-out. i have yet to see an ongoing forge mod that adds this type of stuff independently rather than being a feature in a larger mod. but i also wouldn't mind adding decorations as well such as drinks glasses which can store pam's harvestcraft and farmer's delight liquids or a cooler to store said liquids. i'm still in the drawing board phase right now, so any ideas or feedback would be appreciated!
