Spray medium frying pan with non- stick spray. Scramble eggs and toss for about 5 minutes, or until eggs are no longer liquid. Add spinach, black olives, sun-dried tomatoes and continue to stir/toss until no longer wet. Add feta cheese and cover until cheese is melted. Add 2 tbsp of refried beans to each tortilla. Top with egg mixture, dividing evenly between all burritos. Wrap as shown in video. Grill on panini press (this is what I use) or in frying pan until lightly browned. Serve hot with salsa and fruit (optional) If freezing: wait until cooled, then wrap as directed in video. If you are reheating: Heat in microwave (in parchment paper) for about 2 minutes. Serve hot.
