Cook your pasta in salty boiling water until al dente.
While your pasta cooks, get out a medium/large skillet and toast the panko, rosemary and a pinch of salt.
When the panko starts to brown a little bit, remove it from the pan and set aside.
Wipe out the pan and add drizzle of olive oil, the collard greens, a few pinches of salt, a bit of garlic and a good squeeze of lemon.
Cook until they're mostly wilted (a few minutes).
Add the pasta, and toss with a small dab of butter, a squeeze of lemon, and some reserved pasta water if necessary to loosen it up.
Finish with a drizzle of olive oil.
Remove from heat and toss with the rosemary-panko mixture, toasted almonds, a bit of lemon zest and a pinch of red pepper flakes.
Taste, adjust seasonings.
