01 - Rinse amaranth thoroughly under cold water to remove excess starch.
02 - Bring 1 1/2 cups water to a boil in a small saucepan. Add rinsed amaranth and 1/4 teaspoon salt. Reduce heat to low, cover, and simmer for 20 minutes until water is absorbed and grains are tender. Fluff with a fork and set aside.
03 - Heat olive oil in a skillet over medium heat. Add sliced red onion and sauté for 2 to 3 minutes until softened.
04 - Add minced garlic to the skillet and cook for 1 minute until aromatic.
05 - Add chopped kale to the pan and cook for 3 to 4 minutes, stirring, until wilted.
06 - Stir in halved cherry tomatoes, smoked paprika, black pepper, and red pepper flakes. Sauté for 2 to 3 minutes until tomatoes are just softened.
07 - Divide cooked amaranth into two bowls. Top each with the warm sautéed kale and tomato mixture.
08 - Sprinkle each bowl with crumbled feta cheese, pumpkin seeds, and fresh basil leaves if desired. Serve warm.
