This doesn't matter anymore, but while looking through the Tiny Compendium 2019, I saw a Halfling Heritage. Most of it is irrelevant due to Psybermagi's reimaging with the Duende, however, one of the heritage traits was Halfling Cookpot:
Halfling Cookpot: When Halflings have time to cook, they can spend one hour preparing a meal for their friends. The Halfling may make a Test. If successful, roll 2d3 for a pool of Hit Points. These Hit Points must be shared in total among those who partook of the meal, allowing them to heal. A Halfling may only do this once per day.
So, just as another data point for how to handle such a trait.
Just for fun, they also included these additional options. The first four add abilities to Halfling Cookpot. Do note that the last, Liquid Courage, is completely independent! In a way, it is functionally giving you two healing potions a day for the cost of the alcoholic drink being imbibed.
Gourmet Chef: I learned with the very best, studying under Ramm Zay, Feeary, and more! When making a Test for the Halfling Cookpot Trait, you gain Advantage.
Hundred Weight Feast: Dagda’s Cauldron couldn’t feed as many as I can! It’s also great on salads. When using Halfling Cookpot, you restore 3d3 instead of 2d3.
Fast Food: Whadda ya want, dear? You may use the Halfling Cookpot Trait twice per day.
Exotic Ingredients: I only cook with the very best. Kraken Liver anyone? Each obscure or strange ingredient you add to a dish when you use Halfling Cookpot adds +1 to the total Hit Point pool generated. If you have the Alchemist Trait, you may add +2 instead, but all who eat must make a Save Test or lose 1d3 Hit Points.
Liquid Courage: It might be the beer googles talking, but he don’t look that big... Twice per day, when imbibing an alcoholic drink, you heal 2 Hit Points back.
