Place chopped bacon into a large COLD skillet. Turn on med-high heat and let the fat render from the bacon and cook until crisp. Remove with a slotted spoon and drain on paper towel lined plate.
Remove all but 3 Tbsp. of the bacon grease and add the corn, bell pepper, onion, and green beans. Saute over med-high heat until veggies are brightly colored and just tender.
Add the bacon back into the pan and stir to combine well.
Season with freshly ground black pepper and TASTE before seasoning with any salt as the bacon and bacon grease is already salty.
Toss with fresh parsley and serve!
