Breakfast is the most important meal of the day, to ignore. Don't worry about missing it. First off you'll have to realize that you're not built with a large frame so you should be realistic with just how much muscle that you'll be able to gain and the speed at which you can put on muscle is largely connected to your genetics. That being said some key points to keep in mind to progress at the optimal speed for your body are:
1- Make sure that you're getting enough protein. For you this currently means at least 130g per day.
2- Do the right workouts. Start off with major compound movements, this means squats, deadlifts, shoulder presses, bench presses and pullups. You could honestly get ripped and healthy just doing those, but it'll be almost impossible if you don't do them.
3- Make sure that you know how to work out. Yes this might seem foolish but most people get it wrong (at least most who don't pack on weight). Find a weight at about 70% of your 1 rep max for that movement and move it until you can't anymore AND KEEP TRYING TO MOVE IT. You don't need to do multiple types of exercises on the same muscle groups to get proper muscle fatigue, you just gotta push the first exercise as far as it should go.
4- Measure your progress by the increase in strength, not size or body weight. How much mass your body puts on to adapt to higher and higher resistance is all genetics and there's nothing you can do about that. Just focus on a steady progression of strength and allow your body to build the way it was programmed to.
5- No cardio. Just no.
6- Allow for proper rest. Taxing your muscles by going back to a certain type of exercise too soon can completely halt the production of excess muscle tissue meaning that you're completely blocking any gains you might have made had you just sat at home and cooked a steak instead.
7- Be realistic 1-4 pounds of muscle gained a month is good progress. Anything over 4 pounds is completely unsustainable and really anything over 2 pounds is down to genetic advantages. If you start gaining 2 pounds each month that's an additional 24 pounds in a year. That's about 20% extra you in one years time which is actually a ridiculously impressive improvement.
