Boil a large pot of salted water, add pasta + cook 2-3 min, then drain + return to pot

Meanwhile, heat 2 tbsp oil in a skillet over med-high; add tomatoes + cook 3-4 min until tomatoes begin to burst; pat chicken dry, then slice + add to pan with tomatoes; add olives + 2-4 tbsp water then season sauce with salt/pep; bring all to a simmer 1-2 min until hot

Toss pasta with chicken, sauce + pesto aioli; divide between plates—delish!
