Preheat oven to 200F.
Blanch asparagus tips and green beans in boiling salted water for 2-3 minutes then cold shock and drain. Reserve.
Bring a large pot of water to boil for pasta. Place a serving platter in the oven to warm.
Season chicken cutlets or fish filets with salt and pepper and dredge in flour seasoned with poultry seasoning or Old Bay. Heat 2 tablespoons EVOO and 1 tablespoon butter in a large skillet over medium heat. Saut chicken or fish until lightly golden on each side, 8 minutes. Transfer to warm platter.
Cook pasta to al dente in salted water.
Add remaining 3 tablespoons butter to the skillet and melt. Add garlic and shallots; saut 2-3 minutes. Slice 1 lemon and add it to the skillet along with the juice of a second. Add capers and stir a minute more; add wine and reduce a minute then add stock and parsley. Simmer to thicken a bit then spoon half the sauce over the chicken or fish and cover with foil. Add peas to remaining sauce, the juice of remaining lemon, asparagus and beans, and drained pasta. Toss to combine and season with salt and pepper to taste.
Serve cutlets with vegetable and lemon pasta alongside, garnished with a few leaves of basil or tarragon.
