Slice sweet potatoes lengthwise into 1/4 inch slices. Add to the toaster like you would bread and toast on high. It took me 2 rounds to get it cooked how I like with a little bit a browning on both sides.
Remove skin from avocado and slice. Add to toast and sprinkle with salt, pepper and some lemon zest.
For Almond Butter:
Spread some almond butter on toast and add sliced banana and a bit of cinnamon.
I added 1 tablespoon of mayonnaise, 1 tablespoon relish and 1 tablespoon of diced red onion to a small can of tuna. Scoop tuna onto toast!
