Cooking for different goals

Hey all! I have a question about cooking.

I love to cook and do most of the cooking for my husband and myself. We both workout and are fairly active, and our diet currently consists mainly of real, whole foods.

What I’m trying to figure out is how to best prepare meals for us when we both have nearly opposite body and fitness goals:

My goal: to maintain or slightly decrease my weight.

His goal: to put on up to about 15-25 lbs of muscle mass.

(Of course this is just a portion of both our goals. We also want to stay healthy, build strength, etc. But the above is the relevant part to my question)

Our goals are somewhat opposite. Additionally, he’s very tall and slim, has a fast metabolism, and is not naturally disposed to eat past being full or to eat when he’s not hungry.

Soooo...I’m trying to figure out, how do I cook for such opposite goals? It seems like I need to cook more calorically dense foods for him, but of course with my goals that’s not the kind of food I want/need to eat. But I also don’t want to be making 2 dishes every day. So I’m not sure what to do. Any thoughts or suggestions would be much appreciated!!!
