Start by rinsing the quinoa thoroughly under cold running water. This removes its natural coating, which can taste bitter.
Add the rinsed quinoa to a pot with water and a pinch of salt. Bring to a boil, then reduce heat and simmer covered until tender.
Once done, let it rest for a few minutes before fluffing with a fork. This keeps the texture light and fluffy.
Preheat your oven to a high temperature to encourage caramelization. Toss the corn kernels with olive oil, salt, and pepper.
Spread them in a single layer on a baking sheet. Avoid overcrowding so they roast instead of steam.
Roast until lightly charred and golden. The slight smokiness enhances the sweetness beautifully.
Pat the flank steak dry with paper towels. Season generously with salt, pepper, and a little minced garlic.
Heat a skillet over high heat and add olive oil. Sear the steak for several minutes per side until browned and cooked to your preferred doneness.
Remove from heat and let it rest for at least 5 minutes. This step locks in juices before slicing.
In a blender or bowl, combine sour cream, chopped cilantro, lime juice, remaining garlic, and a pinch of salt.
Blend or whisk until smooth and creamy. Add a splash of water if you prefer a thinner consistency.
Taste and adjust seasoning with extra lime or salt as needed. The sauce should be bright and slightly tangy.
Start by adding a generous scoop of quinoa to each bowl. Spread it evenly as the base layer.
Top with sliced steak, roasted corn, and fresh avocado slices. Arrange neatly for a vibrant presentation.
Drizzle the cilantro cream sauce over everything and serve with lime wedges for an extra burst of freshness.
