6 down, 21 across: Spooner’s out of depression with 13-down (bombproof) snack (5, 5)
The answer works without bombproof: Spooner’s out of depression = Spooner’s from pit = pomme frite = snack.
That’s just as well because the reference to 13-down, the solution to which is bombproof, should actually be a reference to 15-down, the solution to which is deep fryer.
15 down: Soulful cleric employed in Maccas, we hear (4, 5)
Quite a good clue: soulful cleric we hear = deep friar we hear = deep fryer = employed in Maccas.
The problem that you might have noticed with my rearranging of the clue: we hear should be at the start of the clue, not the end.
