INGREDIENTS
1 tbsp. extra-virgin olive oil
1/2 yellow onion, diced
2 lb.  ground beef
2 tbsp. kosher salt
Freshly ground black pepper
2 tbsp. keto taco seasoning mix 
1 jalapeño, seeded and minced, plus more sliced for garnish
6 large eggs, lightly beaten
2 c. shredded Mexican cheese
2 tbsp. freshly chopped parsley leaves
1 c. sour cream, for serving (optional)


























DIRECTIONS
1.    Preheat oven to 350°. In a large skillet over medium heat, heat oil. Add onion and cook until slightly softened, 2 minutes. 
2.   Add ground beef and season with salt and pepper. Cook, breaking up meat with a wooden spoon, until no longer pink, 6 minutes. Sprinkle in taco seasoning and jalapeño and cook, stirring, until spices are lightly toasted, 1 minute. Drain and let cool slightly. 
3.   In a large mixing bowl, whisk eggs, then add in meat mixture. Spread mixture into an even layer in the bottom of a 2-quart baking dish. Sprinkle with cheese. 
4.   Bake until set, about 25 minutes. 
5.    Sprinkle with parsley and top each slice with a dollop of sour cream and jalapeño, if desired.
