If your chicken breasts have the tenders still attached, remove them and freeze them for another time.Then give the chicken breasts a little bash with a rolling pin to flatten them a little.
You don't want to flatten them completely, just get them to "spread" a little.
Crack the egg into a wide, flat bowl and season generously with salt, then add the paprika and beat with a fork.
Sprinkle the flour and bread crumbs onto separate plates.
Take each chicken breast and first coat them with the flour, then dip them into the egg. Finally, coat the chicken breasts with the breadcrumbs.
Heat the oil in an ovenproof frying pan over a medium-high heat. When hot, add the chicken breasts "presentation" side down.Cook until golden, which should take 3-4 minutes.
Flip the chicken and transfer to the oven. Roast at 180°C or 350°F until the internal temperature reaches 74°C or 165°F. This should take 12-15 minutes. Or you can pop them in an air fryer at 180°C or 350°F for 8-10 minutes.
Zest and juice the lime.
Mix together the mayo, sweet chilli sauce, the zest and half of the juice from the lime. Taste and add salt as required.
Thinly slice the cucumber and pick the lettuce.
I like to build my burger in the following order. Bun, mayo, cucumber, lettuce, more mayo, chicken patty, cucumber and more mayo before adding the top!
