Another paranoid (but more specific) school question

So...

We switched over to the school schedule today to get ready for kindergarten in TWO WEEKS. He's been getting up at 7:30 and eating around 8, so I wanted some time to figure things out since he will be getting up at 6:30 and eating at 7. Breakfast has always been pretty tricky for us, but we've been having some consistent and satisfying results over the last couple months, so I wanted to make sure that a schedule change wouldn't affect that. (HA! HA HA!).

So he spikes up to freaking 384, double arrows up. Out the window goes the plan for morning snack- which he usually needs to keep him from crashing post breakfast (just no other way around it). Lunch was supposed to be at 11, but since he got his correction at 9:30, two hours after breakfast (did I say breakfast was supposed to be at 7? Yeah, he was still in bed. Oops.) he wasn't ready to eat lunch until closer to 11:30, because he was still uncomfortably far above target.

So the question is: what happens if it is lunch time at school, and he's high? Like, too high to let him eat high?

At home, we have the luxury of waiting until he comes down. I have the luxury of substituting low or no carb options until he's in range. At school, 30 minutes later means lunch is over. At school, lunch is whatever is already in his lunchbox.

In preschool, we didn't have lunch, but if he was too high at snack time, we'd give him the option of:

a) Hunt's Sugar Free "Snack Pack" (which means Jell-o)

I do not love this option for many reasons, first of all being that I firmly (ha ha) believe that jello-like products need to be cold. There is something scientifically confusing about how this does NOT have to be refrigerated. Which at pre-school was essential, since they would not allow us to use their refrigerator due to licensing restrictions. That isn't the kind of thing we'd normally have a problem with. Just ask my sweet five year old boy who almost spit out his Juicy Juice when he was low last week because it was COLD!! However, that did rule out meat, cheese, raw veggies... so there went our usual arsenal of low carb stuff.

Secondly, because I really hate to give Liam artificial sweeteners (check) and artificial dyes (unless that stuff is red from CHERRIES- no- check). I figure it sucks enough when he has to watch his classmates all eat the same carb loaded snack while he gets something else, so when he said he liked it, I decided to just call it a compromise.

b) Mt. Olive Pickle Pak

No brainer. Tiny, cute carb-free pickles individually packed and sealed so they don't have to be refrigerated. Now, I am totally repulsed by pickles and my husband is a strict Claussen-from-the-refrigerated-section-only SNOB, but these are so convenient that we are going to put our parental issues aside and let the kid eat them.

c) Jerky

We were getting desperate. We won't talk about the bag of fried pork rinds that made their way into my house. As a former vegetarian, the jerky offends me enough.

All is well and good with those, but a lunch they do not make.

We do have a Dexcom that we can monitor to make sure he's close to range as we come in to lunch, but remember he has to eat a snack two hours after breakfast to prevent a crash from the tail on his breakfast bolus. So if breakfast is at 6:45, snack is at 8:45, and lunch is just over two hours later at 11, we don't have much time to see where he is going to land before lunch. It makes me nervous.

How are we supposed to handle this? Any ideas?
