How do you say this in an easier way

I have made up the sentences below.

(A) Suppose that I want to have breakfast only four days every week. The four days are random. For example, the days I choose can be Mon/Tue/Fri/Sun, Tue/Wed/Thu/Fri, Mon/Thu/Sat/Sun, and so on. I want only 1 beef sandwich per day for breakfast. Here is my sentence.

(1) Every week, I go to ABC Supermarket to buy four beef sandwiches for breakfast, one for each breakfast.

(B) Again, suppose that I want to have breakfast only four days every week. I need six cheeseburgers in total.

For example,
I might eat 1 on Mon, 1 on Wed, 2 on Tue and 2 on Sat;

or 2 on Mon, 1 on Fri, 1 on Sat, and 2 on Sun;

or 1 on Tue, 2 on Thu, 1 on Fri, and 2 on Sun;

and so on. The days I choose to have breakfast are also random. Here is my sentence.

(2) Every week, I go to ABC Supermarket to buy six cheeseburgers for breakfast, one for each of two breakfasts and two for each of another two breakfasts.

I hope you understand my difficulty. I am sure that the highlighted phrases are awkward. How do you revise my sentences to convey my ideas clearly? Thank you very much for your time and help. I really appreciate it.
