Chop the onion, pepperoncini, peppadew, lettuce, and tomato into bite-size pieces. Dice the meats and cheese.
Combine the chopped vegetables, meats, and cheese in a large bowl.
In a separate bowl, add the mayonnaise, olive oil, oregano, basil, and red pepper flakes and stir until everything is well mixed. Add dressing to meat and cheese mixture, toss until well combined. Refrigerate until ready to serve.
Carve out the center of the bread boule to make a bowl (don’t cut through the bottom) and cut the scraps into bite-size pieces. Serve the hoagie dip in the bread bowl, with the extra bread and sliced baguette to scoop it up!
