In a large pot, bring salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.
Prepare the Steak and Shrimp:
In a large skillet, heat olive oil over medium-high heat. Add the minced garlic and sauté for about 30 seconds until fragrant.
Season the sliced steak with chili powder, paprika, salt, and pepper. Add to the skillet and cook for about 3-4 minutes until browned but still tender. Remove from the skillet and set aside.
In the same skillet, add the shrimp, season with salt and pepper, and cook for 2-3 minutes until pink and opaque. Remove from heat and set aside.
Make the Mango Alfredo Sauce:
In a blender, combine the diced mango, heavy cream, Parmesan cheese, butter, hot sauce, salt, and pepper. Blend until smooth.
Pour the sauce into the skillet over medium heat, stirring until heated through.
Combine Everything:
Add the cooked pasta to the sauce, tossing to coat evenly. Then, return the steak and shrimp to the skillet and gently mix until everything is well combined and heated.
Serve:
Divide the pasta among serving plates. Garnish with fresh cilantro or parsley and lime wedges if desired.
