Pat the ribeye steaks dry and drizzle lightly with olive oil. Season generously with Montreal steak seasoning, smoked paprika, and kosher salt, pressing the seasoning into the meat.
Heat a pan over medium-high heat and add a little neutral oil. Once hot, add the steaks and cook for about 3–4 minutes per side, depending on thickness and desired doneness. Remove from the pan and let rest for at least 5–10 minutes before dicing into bite-sized pieces.
While the steak rests, prepare your vegetables. Dice the cucumber and bell pepper, thinly slice the radishes, and chop the tomatoes. Add everything to a large bowl.
In a blender or food processor, combine the cilantro, garlic, olive oil, balsamic vinegar, lemon juice, salt, and white pepper. Blend until smooth and well combined.
Add the diced steak to the bowl with the vegetables. Drizzle the dressing over top and toss gently until everything is well coated.
Serve immediately and enjoy
