In a small saucepan, heat 1/2 teaspoon oil over medium. Add couscous; cook, stirring, until lightly toasted, 1 to 2 minutes. Add 1/2 cup water and garlic; season with salt and pepper. Bring to a boil; cover, and reduce heat to low. Cook until liquid is almost absorbed, about 6 minutes. Add spinach, and cook until couscous is tender, 1 minute. Stir in almonds, and set aside.
Sprinkle chicken with garam masala; season with salt and pepper. In a small skillet over medium-low, heat remaining 2 teaspoons oil. Add chicken; cook until opaque throughout, 6 to 8 minutes per side. Slice chicken; serve with couscous.
Garam masala is a fragrant Indian blend of spices that usually includes black pepper, cinnamon, cardamom, cumin, and coriander. As with regular couscous, Israeli couscous is a type of pasta made with semolina flour, but its grains, or pearls, are larger and chewier.
