Take out a cutting board and a knife.
Dice your potatoes into about ½ inch pieces. Dice your red onion and dill pickles. Halve your cherry tomatoes. Shred your cheese if it's not pre-shredded. Set everything aside for now.
Take out a large skillet and turn a burner to medium heat.
Add your diced potatoes along with the smoked paprika, garlic powder, onion powder and a pinch of salt and pepper. Cook them for 15 to 20 minutes while occasionally moving them around. Cook until they're crisp on the outside and fork-tender inside.
Transfer your potatoes to a bowl and set aside for now.
Add your ground beef to the skillet. Break the meat apart with a spatula and cook for 7 to 9 minutes until fully browned and no longer pink. Drain any excess fat if needed. Then season with Worcestershire sauce, mustard, salt and black pepper. Set aside for now.
Take out a small bowl to prepare your big mac sauce.
Add your Greek yogurt, ketchup, mustard, dill pickle juice, garlic powder, onion powder, smoked paprika and a pinch of salt and pepper. Mix everything together until smooth. Taste and adjust with extra salt, pickle juice or ketchup if you prefer. Set it aside for now.
Let your cooked beef and potatoes cool for 30 to 60 minutes at room temperature. This prevents excess condensation and sogginess once the containers are sealed and refrigerated.
Take out five 35 oz meal prep containers.
Add your shredded romaine lettuce as the base layer in each container.
Top each container with roughly equal portions of your cooked beef, potatoes, shredded cheese, diced red onion, halved cherry tomatoes and diced pickles.
Seal your containers and refrigerate for up to 4 to 5 days. Keep your Greek yogurt sauce in separate small containers and add it to each bowl only when ready to eat to keep the lettuce crisp.
When ready to eat, drizzle the desired amount of sauce over your bowl, toss if desired and serve.
