Potato Mac Salad (to go with your Hamburger Steak)

This was the best potato mac salad I ever made.  And the only . . . 

I looked at recipes online and kinda made up my own.

Throw together:

One good-sized potato, microwaved for 6 minutes, skinned and cubed

1 cup-ish macaroni, boiled and drained

2 boiled eggs, diced

1 can tuna, drained

1/2 cup (maybe more?) mayo

carrots, shredded

cilantro, minced (cause I had)

2 teaspoons onion powder (cause Landon doesn't like raw onions)

salt (sprinkle)

pepper (planny if you're Cy)
