Pro Tips Before You Start

Toast bread carefully: Watch the broiler! Toasted side should go inside the sandwich.

Use thick Greek yogurt: This helps keep the spread rich and stable.

Season your veggies: Salted tomatoes and cucumbers = flavor boost and less sogginess.

Let onions marinate: The longer they sit, the better they taste.

How to Make the Ultimate Veggie Sandwich

Step 1: Pickle the Onions
Add thinly sliced red onion to a small bowl.

Squeeze in fresh lime or lemon juice and season generously with salt and pepper.

Stir occasionally while prepping the rest.

Step 2: Make the Cream Cheese Spread
Stir softened cream cheese until smooth, then mix in Greek yogurt.

Season with salt, pepper, onion powder, and stir in chopped dill, parsley, and chives until creamy and evenly combined.

Step 3: Toast the Bread
Move oven rack near the broiler and preheat.

Lay out sourdough slices and butter the tops if desired.

Broil for 2–4 minutes, watching closely, until golden on top.

Step 4: Prep the Tomatoes
Slice tomatoes and place them on paper towels.

Season with salt and pepper, then flip after a few minutes and repeat on the other side.

Step 5: Make the Avocado Spread
Mash avocados with lemon juice and salt until smooth.

Taste and adjust salt if needed.

Step 6: Slice the Cucumbers
Use a mandolin or sharp knife to thinly slice the cucumber. Set aside.

Step 7: Assemble the Sandwich
Stir the cream cheese spread again.

On one toasted side of the bread, spread the cream cheese.

On the matching piece, spread the mashed avocado.

Layer on tomatoes, cucumber, sprouts, pickled onions, optional cheese, and spinach (which sticks to the avocado).

Step 8: Slice and Serve
Cut the sandwich in half—triangle or rectangle is your call.

Serve immediately and enjoy every crunchy, creamy bite!
