• Heat a large skillet over medium heat.
• Add the lean ground beef to the skillet, breaking it apart with a spatula.
• Cook the beef, stirring occasionally, until it's browned and cooked through.
• Strain the meat to remove excess grease.
• Add the diced tomatoes and taco seasoning. (You may need to add a bit of water as well, if it seems dry)
• Simmer for a few moments until heated through.
• Turn off the heat and stir in the chopped cilantro.

Prepare Shredded Lettuce:

• In a separate bowl, toss shredded lettuce with a generous squeeze of fresh lemon juice and salt.

Warm the Tortillas:

• While the beef is cooking, warm the tortillas. You can do this by wrapping them in a damp paper towel and microwaving them for about 20-30 seconds. Alternatively, you can heat them on a dry skillet for about 10-15 seconds per side.

Assemble the Tacos:

• Spoon a generous portion of the seasoned and cooked beef onto each tortilla.

Add Lettuce and Toppings:

• Top the beef with a handful of the prepared shredded lettuce.
• Add any other desired toppings such as shredded cheese, salsa, guacamole, or sour cream.
