Preheat oven to 450°; drain beans, rinse + pat dry; toss with 1-2 tbsp oil, salt/pep + your fav seasoning (we like Garlic and Herb or Taco Seasoning); scatter beans on a sheet pan, roast 25-30 min, flipping 2-3 times throughout cooking, until beans are crisp on the outside but soft in the middle

Meanwhile, discard outer leaves from 1 head of lettuce, cut off stem, wash + dry; slice into 4 wedges + add to plates

Cut onion in half from root to stem + peel; thinly slice ½ onion, then slice ½ cup tomatoes in half

Dress each wedge with 1-2 tbsp sauce + salt/pep; scatter veggies + crispy beans over top
