Pablanos are a good pepper, I normally stuff them with a mixture of cheese and hot italian sausage and grill them. I do the same with Hungarian Hot Wax peppers. I made a tray to hold my ABT's and ADT's so I just cut the tops off, stuff and cover the top with a 1/2 slice of bacon. They do not need sealed completely because they are cooked standing upright.
Here are a few stuffing suggestions for either ABT's or ADT's:
1) Three cheese, name says it all, cream cheese, cheddar cheese and hot pepper cheese. Or any cheeses you prefer. Top with bacon slice.
2) Taco, Make up a batch of taco meat filling, after cool mix in cream cheese and stuff the peppers.
3) Sausage & cheese, bulk sausage with any cheeses mixed in.
4) Cheese and bacon, cream cheese and any other cheese you like, mixed in with fried chopped bacon.
5) Cheese, bacon and leek, like above but mix in chopped wild leeks. MMmmmm
Filling ideas are endless. Enjoy.

This is a pic from the internet but you can see how the peppers sit in the pan to cook

EDIT:
I forgot to add, if you have any left over brisket or pulled pork, chop it up and mix in some cheese, top with bacon and your in heaven!
