Brown the beef: Heat a large skillet over medium-high. Add ground beef and cook, breaking it up, until no pink remains and moisture cooks off, 6–8 minutes.
Season it right: Sprinkle in taco seasoning and 2–3 tablespoons water.
Stir and simmer 1–2 minutes until well coated. Taste and adjust salt if needed. Let it cool to room temp.
Mix the dressing: In a bowl, whisk Greek yogurt, lime juice, olive oil, cumin, salt, and pepper.
You want a spoonable, creamy dressing. Thin with a splash of water if too thick.
Prep the veggies: Halve tomatoes, dice onion and bell pepper, rinse beans, drain corn, and chop greens. Pat veggies dry so excess water doesn’t pool in the jars.
Layer smart: Start with the thickest, wettest ingredients at the bottom.
This protects delicate greens up top.
Build the jars: Bottom: 2–3 tablespoons Greek yogurt dressing, then 2 tablespoons salsa.
Next: 1/3 cup black beans, 1/4 cup corn.
Then: 1/3–1/2 cup cooked seasoned beef.
Then: Bell pepper, red onion, and cherry tomatoes.
Top: A generous handful of lettuce/greens and a sprinkle of shredded cheese.
Seal and chill: Screw on lids and refrigerate up to 4 days. Keep jars upright so dressing stays at the bottom.
Serve: Shake the jar gently, then pour into a large bowl. Add avocado, cilantro, and a squeeze of lime right before eating.
