What are the best methods and foods to achieve the ideal amount of macronutrients without getting bloated?

[gabrihell]

I wanted at least some suggestion on how to achieve this,

I need goods and cheap food that doesn't have any problems and that I can get and eat at any time.

For example, I was thinking about eating sweet potatoes because they are easy to access and have a low GI, but after doing some calculations I realized that I would have to eat like 2kg of potatoes to get the carbohydrates for the day, what makes it unfeasible
I also thought about eating oats but it's very difficult to eat them in large quantities.

proteins seem to be the hardest, please I need help to gain weight
I'm tired of not making gains in the gym by just eating healthy foods
(I'm also using beans to get potassium)

Meat, dairy, eggs.

1. Red meat

2. 3 eggs

3. A stick of butter

You will never feel bloated if you eat this once a day as your only meal. Nothing else.
