Heat 1 tbsp. oil in a large nonstick frying pan over medium heat. Add garlic and cook until fragrant, stirring, about 30 seconds.
Add dandelion greens in batches, turning frequently with tongs. Increase heat to medium-high, sprinkle with salt and pepper, and continue to cook, turning with tongs, until greens are wilted and tender-crisp, about 5 minutes.
Add currants and pine nuts and cook 1 minute more. Transfer to a serving dish and drizzle with about 1 tbsp. more oil. Serve with a squeeze of lemon if you like.
