"Sandwich?" That sounded easy enough! Feh! He'd either rock this sammich and show her good, or fail and poison her. Win win.
"Microwave brownies..?" Otto blinked and shook his head. What the ******** were those? Well, whatever.
Otto got to work.
Bread.
Check.

Mustard? Slab that s**t on there!
Bitches love Mustard.
Otto don't get skimpy on that s**t, okay? Gotta cover all the bread. Nothing worse than a dry patch in your sammich! He's just looking out for you, Rin!
Next up! Cheese. Yeaaaah lots of damn cheese.
Hm? Cream cheese? That's like, half the work of chewing done for you, right? DO IT!

<******** Yeah! Otto was a Lunch Master! Okay, what was next.. Fritos? On a sandwich? Well.. WHATEVS! But hm.. it'd be too pointy to just slap them on there...

Genius. Frito Powder! Turning that boring cheese into a healthy colour, yeah!
And now.. the meat! Lot's of meat. Rin looked like she enjoyed big meat.
What was that? She didn't ask for mea---TOO ******** BAD.

So pro.
Seemingly done, Otto smooshed the two pieces together, flopped it onto a plate and placed it on the table.
"No dessert till ya eat yer lunch."
