Pickle as many as you can. If you have larger milder varieties like Giant Marconi, Anaheim, Poblano, etc you can also stuff those and freeze them. 100 plants? I have trouble keeping up with the 24 I planted, I've got about 40 banana peppers I still have to pickle real soon.
I have about 5 tomato plants and so far I've had to make salsa and pasta sauce from scratch a couple of times to use them all.
I forgot to mention hot sauce. There's a stickied thread on how to make it, with 100 plants I'd be willing to bet you have lots of each variety? That means you can make a lot of pure sauce (sauces made from only 1 type of pepper). A couple years ago I had 100's of habanero peppers and I made a pure orange habanero hot sauce, I still have some 2 years later and its delicious.
