I want to make him a little mix of stuff to eat, so here's some stuff that I found that 'might' be OK?

Roasted peanuts (With or without shell, or no peanuts at all?)
Original Sunflower Seeds (The David's brand, is that OK to feed?)
Ritz crackers
Carrots
Rice Krispies and/or Frosted Flakes (Are those OK to feed?)

That's all that I found in my house that I thought would be fine, I haven't made it yet but I want some opinions first on what to take out and stuff.
