Looking for advice from passive, mindless snackers

It's a fantasy of mine to gain weight through passive, mindless snacking. Training myself to always been munching on something because I have endless supplies of food and drinks around my bedroom that I pick at without thinking. I was wondering if anyone has suggestions for what supplies I should buy. I want to up my gain and my game! I work from home too so this would encourage me to snack while I work. I am looking for both healthy and not so healthy foods that might boost my gains. Thanks in advance 🙏🏻
