I've made this before but forgot to take a picture of it! Now I can share a super simple recipe that you can use if you're short on time or just don't feel like putting in an hour + on dinner!
3/4 c. butter, softened 1 envelope Italian salad dressing mix 6 hoagie buns, split 12 to 16 oz. luncheon meat (whatever you love!) 12 thin slices cheese (you choose!) Combine butter and salad dressing mix; spread 1 tablespoonful inside each bun. On bottom of each bun, layer one slice of meat, two slices of cheese and another slice of meat; replace tops. Spread 1 tablespoon butter mixture over top of each bun. Place on a baking sheet. Broil 6 in. from heat for 2-3 minutes or until tops are lightly browned.
Personally, I like having the first meat layer turkey, then swiss, then ham. Easy quick meal!
