Heat 3 tablespoons of the butter in a saucepan over medium-high heat.
Add the chicken strips and cook until browned and cooked through, about 4–6 minutes depending on thickness; transfer the chicken to a plate.
Reduce heat to low, add the honey and soy sauce to the pan with the remaining butter, stir to combine and heat briefly until sauce is glossy; return the chicken to the pan and toss to coat. Season lightly with salt and pepper to taste.
Meanwhile, heat the olive oil in a large skillet over medium heat.
Add the crushed garlic, chopped yellow pepper and chopped red onion and sauté until softened, about 4–5 minutes.
Remove the pan from the heat, stir in the smoked paprika, and season with salt and black pepper to taste.
Combine the sautéed vegetables with the cooked couscous in a bowl and mix thoroughly.
Stir the chopped basil into the couscous mixture.
Serve the couscous on plates and top with the honey-soy chicken strips.
