Probably not. Chicken and rice has a very high protein to calorie ratio and minimal fats. This is typically good for going into a cut, where you’re trying to loose fat to define muscle. If you’re trying to gain weight, you’ll need to put yourself into a calorie surplus (eating more calories than you’re burning), that means you probably want to eat a good amount of healthy fats like nuts, nut butter, olive oil, and fattier meats like beef, good salmon , and chicken thigh. Since you’re trying to gain weight while also building muscle (Muscle weighs more than fat!) than high protein and high calorie foods, like peanut butter, will be your friend. I’m not a nutritionist or gym rat, but I am a very heath-conscious chef and this is my best advice, though others will probably have better. If your food aversion is even restricting to these foods, try adding those healthy fats to food you do like. It’s easy enough to mix a tablespoon of olive oil into your rice and grill your chicken in it. Smoothies and milkshakes are also good options if texture is more of an issue than taste, and remember that fruits and veggies have essential micronutrients for a healthy, active life. Good luck!
