Heat 1 tbsp (15 mL) olive oil or butter in a large frying pan and set over medium-high. When hot, add 2 minced garlic cloves, 1/2 cup (125 mL) cashews and 1 tsp (5 mL) cumin seeds. Stir until fragrant, about 1 min. Add an 8-oz (227-g) bag of fresh spinach or 1 large or 2 small bunches, trimmed. Stir until spinach is wilted, about 3 min. Pan will be very full, so you may need to add spinach gradually. Squeeze 1 tbsp (15 mL) juice from lemon overtop. Sprinkle with 1/8 tsp (0.5 mL) salt. Stir to mix.
