My husband needs to gain weight 🤦🏻‍♀️

Okay ladies, I need y’all’s help! Soooo my husband is 6’4” and weighs 148lbs 😅 he eats ALL. THE. TIME.! He shattered his jaw about 5 years ago, had his mouth wired shut for 2 months and lost a bunch of weight. He was up to 210lbs and dropped down to 120/130lbs. Before we moved into our tiny house, I had dinner cooked every night when he got home and plenty of leftovers to take to work the next day. He got up to about 165lbs. He then broke his femur and lost some weight and he seems to not be able to put any weight back on. I don’t cook as much anymore because our tiny home doesn’t have a full kitchen so we mainly eat takeout. He’s tried protein shakes and muscle milk powder. He’s currently trying Ensure but it’s so expensive so I need suggestions on what he could include into his meals to help him gain weight fast. If I could transplant my fat into his body, I definitely would 😅

Edit: HE wants to gain weight! I’m not forcing him to gain weight nor bashing his weight. For his height, he is 8lbs under weight. He should be 156-204. He wants to get back up to at least 200lbs. I am just reaching out to others for suggestions on how to help my husband reach his goal weight. He wants to gain weight because he is a bull rider and he’s tired of being slammed in the dirt with no ass to bounce off of. And he also feels better when he’s filled out. Supporting my husband, as a wife should 😌
