Possibly the first Anderson tale I've enjoyed in an age, well done for breathing some life into this, I know its basically Mai the sidekick's hot dog run, but its highly enjoyable.
Strangely I thought I'd read the Dredd before... my dotage is getting worse 
Yeah, I'll echo the general approval for McHugh's
What If The X-Men Did The Hotdog Run? story. Goddard's art is great, too.
This episode felt like unnecessary backfill, but it's a relief to read an Anderson story where you can tell what everyone's doing, why, and how events in one panel lead into and have a causative effect on what's happening in the next panel, for a change.
I pretty much agree with the consensus on the other stories, too. Nothing awful.
