Okay "chakula cha asubuhi" is a literal translation. For more accuracy you'd be better off saying "kiamsha kinywa" (which literally translates to "that which wakes up the mouth")

For supper, rather than saying "chakula cha jioni", say "chajio/kilalio" (which literally translates to "what I'm sleeping on") #doesn't make much sense, I know. Any way that comes easiest though is fine.

What's the literal translation?

How come you can't say Chakula na asubuhi or Chakula ya asubuhi?
