Heat a pan over medium heat. Add the bacon (lašiniai) and cook until crispy. Remove bacon from the pan, setting aside on paper towel to drain. Reserve a little bacon fat in the pan if desired.
Slice the tomatoes and mozzarella into rounds. Pat mozzarella dry with paper towel if it's very wet.
Cut the herring fillet into bite-sized pieces.
If using the reserved bacon fat or a little oil, lightly toast the bread slices in the pan until golden brown. Alternatively, toast bread in a toaster.
Assemble your stacks: Place a slice of toasted bread on a plate. Layer with tomato slices, mozzarella slices, herring pieces, and the crispy bacon.
Season with salt (go easy, herring and bacon are salty!) and black pepper. Add optional red onion slices and fresh herbs if using.
Serve immediately, perhaps with a glass of milk or kefir on the side if you dare! 😉
💡 Pro Tips & Fun Facts:
- 🐟 Serving herring cold is key! Its texture and flavor shine best that way.
- 🥓 Make sure your bacon is super crispy for that delightful crunch contrast.
- 🍞 Toasting the bread really helps it stand up to the layers and adds flavor.
- 🥛🥛 Kefir or milk on the side? Why not! Embrace the dairy destiny. Or, use a tiny splash of milk to thin out a tomato-mozzarella mash if you want a 'sauce'.
- 🌿 Feeling fancy? A sprinkle of fresh dill or chives (if you have any!) would totally elevate this stack! 🌱
