Make the Cream Cheese Filling:
Take cream cheese out of refrigerator 30-60 minutes before starting to soften to room temperature
In a mixing bowl, combine softened cream cheese, mustard, garlic powder, chopped scallion greens, oregano, and salt
Mix together thoroughly until smooth and well combined
Taste and adjust seasoning if needed
Add the Vegetables:
Add chopped cucumber, chopped bell pepper, grated carrots, corn kernels, and chopped jalapeño to the cream cheese mixture
Fold and mix until all vegetables are evenly distributed throughout the filling
Set filling aside
Prepare the Bread:
Using a sharp serrated knife, cut the crusts off all bread slices
Lay out all crustless bread slices on your work surface
Spread a thin, even layer of sriracha on every slice of bread (both sides that will form the sandwiches)
Assemble the Sandwiches:
Take half of the bread slices and spread 3-4 tablespoons of the vegetable cream cheese filling on each slice
Spread filling evenly to the edges
Top each filled slice with another sriracha-spread slice to create complete sandwiches
Press down gently to seal without squishing out the filling
Chill Before Serving:
Take a clean, thin kitchen towel and dampen it with water (wring out excess so it's moist but not dripping)
Arrange assembled sandwiches on a plate or tray
Cover completely with the damp towel
Refrigerate for 1-2 hours to allow flavors to meld and filling to firm up
Serve:
Remove sandwiches from refrigerator and uncover
Serve whole or cut into triangles, rectangles, or finger sandwich shapes
Arrange on a serving platter and serve immediately
Storage Tip: Best made 2-4 hours ahead. Can be kept refrigerated under a damp towel for up to 8 hours. Do not make the night before as vegetables will release moisture and make sandwiches soggy.
