For a spicier kick, add a teaspoon of crushed red pepper flakes to the meat mixture. You can also substitute ground turkey for a leaner option. If you're gluten-free, use gluten-free breadcrumbs or oats instead. For a different flavor profile, try using a barbecue sauce glaze instead of honey mustard. Feel free to add chopped bell peppers or grated carrots to the meat mixture for extra veggies and texture.
