Rinse fresh spinach under cold water and let it drain.
Chop garlic finely.
In a large skillet over medium heat, add olive oil.
Once hot, add minced garlic until fragrant, about 30 seconds.
Toss in the spinach until wilted but still vibrant green.
Stir in the drained white beans gently, warming them for about two minutes.
Squeeze fresh lemon juice over the mixture along with salt, pepper, and red pepper flakes if using.
Toss everything together until well combined and heated through.
Transfer the dish to serving bowls and drizzle with more olive oil if desired.
