Ingredients

• 1 avocado
• 1 tablespoon mayonnaise
• 3 teaspoons fresh lime juice (or 2 tsps fresh lemon juice)

• 1/4 cup thinly sliced scallion
• 1 tablespoon minced fresh cilantro, to taste
• 1 1/2 lbs lean ground beef

• 1 1/2 teaspoons ground cumin
• 1 1/2 teaspoons dried oregano
• 4 slices monterey jack cheese or 4 slices cheddar cheese
