Cook trimmed green beans in boiling water for 10-15 minutes, or until crisp-tender.
While beans are cooking, melt butter over medium heat and add in almonds. Stir until almonds are golden brown. Pull off heat and stir in salt, pepper, lemon juice and lemon zest. Stir to blend.
Drain cooked beans well and toss in almond mixture. Serve alongside your favorite main dish. Enjoy!
