Step 1: Prepare the Ingredients
Wash and chop the romaine lettuce into bite-sized pieces. Halve the cherry tomatoes. Dice the avocado (squeeze a bit of lime juice over it to prevent browning). Drain and rinse the black beans and corn if using canned. Gather all your toppings and place them in small bowls for easy assembly.

Step 2: Cook the Ground Beef
Heat a large skillet over medium-high heat. Add the olive oil and let it warm for 30 seconds. Add the ground beef and break it up with a wooden spoon. Cook for 5-7 minutes, breaking up the meat into small crumbles as it browns. Stir occasionally to ensure even cooking.

Step 3: Drain Excess Fat
Once the beef is fully browned with no pink remaining, carefully tilt the pan and spoon out or drain excess grease. You want to remove most of the fat but leave a little for flavor. Return the pan to the heat.

Step 4: Season the Meat
Add the taco seasoning and ¼ cup water to the cooked beef. Stir well to combine, coating all the meat with seasoning. Let it simmer for 2-3 minutes until the liquid has mostly evaporated and the seasoning has thickened into a flavorful coating. Taste and adjust seasoning if needed. Remove from heat and let cool slightly.

Step 5: Assemble the Salad Base
In a large salad bowl or on a serving platter, spread the chopped romaine lettuce as your base. You can also divide the lettuce among individual serving bowls if you prefer individual portions.

Step 6: Layer the Ingredients
Add the seasoned taco meat on top of the lettuce while it’s still slightly warm. Distribute the cherry tomatoes, black beans, and corn evenly over the salad. Sprinkle the shredded cheese generously over everything (the warm meat will slightly melt it, which is perfect!).

Step 7: Add Fresh Toppings
Top with diced avocado, dollops of sour cream, and spoonfuls of salsa. Sprinkle with fresh chopped cilantro if using. Add the crushed tortilla chips just before serving so they stay crunchy.

Step 8: Dress and Serve
Drizzle the entire salad with lime juice and add a pinch of salt and black pepper. Toss everything together at the table, or let each person customize their own bowl with their preferred toppings. Serve immediately while the meat is warm and the lettuce is still crisp!
