Southern Bubble & Squeak

Ingredients
2-3 cups cold Boiled Potatoes that have begun to break down, or leftover coarsely Mashed Potatoes. 2 cups or Shredded Fresh Collards with stems already removed (Southern)
Or Cabbage (Traditional). Note collards work better uncooked, but cabbage can be cooked or uncooked.
1 Cup Diced Onion or Shallots
3 Garlic cloves diced
1 Tbs Dijon Mustard
2 Tbs Unsalted Butter
1 Tbs Vegetable/Canola Oil
Method
Gently Heat Butter in a Dutch oven or similar pan, until melted. Add Onion & Garlic & fry 3-5 minutes until translucent.
Add Collards/Cabbage & stir so everything is well coated. Cover & sweat for another 5-10 minutes, until greens are tender.
Add Potatoes & stir. Cover & let cook until heated through (10-15 minutes).
In a frying pan heat the Vegetable Oil & add the Potato mixture. Fry until browned (3 mins per side)
