How can I share recipes that I have in my recipes with another user

You can’t really share recipes at this point. She can take the final result by copying one of your meals with it, then she’d have the resulting calorie and macro count as a food. But she wouldn’t have the list of ingredients to alter.

A better option would be for you to use the “meals” function instead of recipes. Meals can be shared between friends and can be altered after sharing. Try it out, you’ll see it functions pretty similarly to recipes and people who want to share them tend to like it better.
