Instructions

1. Step 1: Preheat oven to 425°F. In a bowl, whisk together 3 tbsp olive oil, 2 tbsp fresh lime juice, 3 cloves minced garlic, 1 tsp smoked paprika, 1 tsp ground cumin, 1 tsp salt, and 1/2 tsp black pepper to create a marinade.

3. Step 3: Meanwhile, boil 2 cups peeled and chopped cassava in salted water for 10 minutes until just tender, then drain.
4. Step 4: On a large rimmed sheet pan, spread the parboiled cassava chunks and 1 cup pineapple chunks. Drizzle with 1 tbsp olive oil and sprinkle lightly with salt.
5. Step 5: Place the marinated flank steak in the center of the pan and roast everything in the oven for 15-18 minutes until the steak reaches medium-rare and cassava edges caramelize.
6. Step 6: Remove from oven and let steak rest for 5 minutes before slicing thinly against the grain.
7. Step 7: Sprinkle 2 tbsp chopped fresh cilantro over the cassava and pineapple before serving alongside the sliced beef.
