I use mealie exactly as your use case describes. We meal plan each week using the recipes I have saved in it and then create a shopping list of those items added to the meal plan. It works great and with docker has been easy to maintain. I used to use Nextcloud Cookbook but I like the UI of mealie better.

Could you forward your X display in an SSH session so you don’t need a webui? I second the vote for handbrake, it’s a great program!
