Open-faced Sandwiches

I made these little beauties so long ago, but the idea of them has been alive in my imagination ever since:

It's a very simple idea--the tray of open-faced sandwiches--but it offers such tastiness and opportunity for creativity that it's worth spending some time with.

In this particular incarnation, we have (across from the top row):
  • Hummus with carrot-broccoli stem slaw
    • Spread home-made or store-bought hummus on a piece of bread.  Top with slaw (shredded carrots and broccoli stems--or throw in any shredded veggies you want!--mixed with a little olive oil, apple cider vinegar, salt, and a tiny bit of sugar)
  • Tomato-basil
    • Mix chopped tomatoes (fresh are best, but canned and drained will do in a pinch) with a large quantity of chopped basil. Taste and season lightly with salt and pepper, if needed.
  • Mashed avocado with yellow pepper
    • Mash one avocado with a little salt and lime juice, if you have it on hand. Spread it thickly on a piece of bread, and lay something crunchy, like sliced yellow bell peppers, on top.
All served on fresh-baked bread! (but done the easy way--in the bread machine).

So delicious and versatile! What ideas would you come up with?
