Freeze steak for 40 minutes. Thinly slice steak against the grain into strips; season with salt and pepper. Warm 1 tablespoon olive oil in a large, nonstick skillet over medium-high heat. Add steak in batches; stir-fry until meat is no longer pink. Remove steak from skillet; keep warm.
Sauté onion and peppers in remaining oil in the same skillet over medium heat for 4-6 minutes or until crisp-tender. Season with salt and pepper. Remove from the heat. Add steak to skillet; toss to combine.
Heat oven to 400°F. Line a 15 x 10-inch baking pan with parchment paper. Arrange tortilla chips in a single layer on prepared pan. Sprinkle with 1 cup Havarti and 1 cup Gouda. Layer with half of the steak-veggie mixture. Repeat layers, starting with 1 cup Havarti. Sprinkle with remaining Havarti and Gouda. Bake for 10-12 minutes or until the cheeses are melted.
Garnish with Odyssey Greek Sour Cream and sliced green onions. Serve immediately.
