Quick and adaptable frittatas are a weekly staple in my household, and I love egg sandwiches in any form. So I can't explain why it took me so long to discover this genius use of leftovers: the frittata sandwich.
Frittatas make ideal leftovers, but slipping a slice between two pieces of bread makes it even more portable. Although frittatas are flavorful enough on their own, a little onion jam, red pepper spread, or even curry ketchup would make this type of sandwich even better.

This is exactly like a common sandwich in Spain that used tortilla espanola (spanish omelete with potato) on a baguette. Delicious!
I am loving your posts today! I make my daughter - most recently summer squash, zucchini and gruyere and also avocado, cheddar cheese and black pepper. Then we (b/c I steal a few) put them on a toasted english muffing with a slice of cheese for an easy sandwich.

I'm with @CST, above. The tortilla sandwich is the GREATEST sandwich of all time.
Another voter for the Spanish bocadillo!!!
If I fancy an extra layer of taste (other than egg & potato-y goodness) I like to add onions and rocket :)
YUMMMM I can totally eat this any time of the day!

Amen to the bocadillo de tortilla! (o de calamares...)
