Prepare the seasoning. In a small bowl, mix together all dry ingredients. Add olive oil and lemon juice and stir well.
Pour prepared seasoning over sliced beef and toss well. Cover with plastic wrap and transfer to the fridge for at least 30 minutes.
Turn the “saute” mode on your instant pot. Pour in olive oil and wait until hot. Add beef slices and saute for 4-5 minutes or until browned. Take the beef out of the instant pot.
Add onion and garlic and saute for 3-4 minutes. When onion and garlic become soft, return the beef to the pressure cooker.
Pour in beef broth and apple cider vinegar and stir well. Close the lid and turn the valve to “sealing.” Press “pressure cook” (manual) and cook at high pressure for 9 minutes.
Once the cooking time ends, let the pressure release naturally.
Arrange a bed of lettuce in each bowl and top with the beef slices, tomatoes, cucumbers and red onion. Drizzle with dressing and enjoy.
