Preheat oven to 350°F.
Cut the jalapeños into a boat cut. (Click the link above to see how to do a Boat Cut.)
Sprinkle insides of cut jalapeños lightly with salt and pepper, to taste.
Place the jalapeños on a cookie sheet. Place sheet in preheated oven. Cook for about 10 minutes. (Skip this step if you prefer your finished jalapeños to be more raw and crunchy.)
Remove from oven and set aside to cool slightly so you can handle them.
In a small bowl, combine about 1/2 cup Kentucky beer cheese, 1/4 cup chopped green onions and 1/4 cup cracker crumbs. Add in 1 tablespoon Worcestershire Sauce. Mix well.
Taste mixture, keeping in mind that the onions will caramelize and sweeten during cooking.
Add salt and freshly ground black pepper, to taste, and adjust other ingredients to your taste preference.
Fill each jalapeño with a generous helping of the Kentucky beer cheese mixture.
Generously sprinkle cracker crumbs over the top of each jalapeño. Press down very lightly to set into cheese mixture slightly.
Place jalapeños back on cookie sheet and place back in oven.
Cook, watching closely, until beer cheese is just beginning to bubble, about 10 - 15 minutes.
Turn oven to broil.
Broil, watching closely, just until cracker crumbs on top brown slightly.
Remove from oven and place on plates or serving platter.
Sprinkle with reserved green onion slices, to garnish.
Serve with lime halves or wedges.
