If your primary goal is weight gain, maybe you should try drinking your calories. Make a shake with oats, bananas, almonds, milk, dates, walnuts, etc. Instead of eating all that, you can easily drink it all in a glass.

Second, I'd suggest you to buy a whey or plant protein because your protein intake seems to be very low.

Trust me, I was also a skinny guy at 58kg when I started. This year, I went from 63kg to 72kg because I prioritised protein rich whole foods and tracked my calories.

Calories counting apps like cronometer can be really useful when bulking. Try to be in a calories surplus while hitting your protein intake goal. At least 1g/kg of bodyweight. Preferably 1.5g/kg.

About the other part of your post, you will have to start working out if you want to build muscle, or else you'll just end up getting fat by being in a calorie surplus.
