Preheat oven to 450°; drain beans, then rinse + pat dry; toss with 1-2 tbsp oil, salt/pep + blackening seasoning; scatter beans on sheet pan + roast 25-30 min, flipping 2-3 times throughout cooking, until beans are crisp on the outside but soft in the middle (or air fry at 380° for 10-12 min til crispy)

Meanwhile microwave 2 sweet potatoes in their wrappers on high, 6-8 min, flipping halfway through (caution, that's a hot potato!); carefully cut in half

Heat 1 tbsp oil in skillet over med-high + cook veggie mix with salt/pep 3-5 min until tender

Add sweet potatoes to plates; top each with veggies + beans then drizzle on ranch-Veggies never looked so good!
