Choose prime produce based on its firm texture, vibrant colors, and perfect skins; smell earthy or sweet aromas; gently squeeze to produce ripe produce (melons, avocados, etc.). Instead of wilting or pre-cut, choose seasonal, busy vendors (high turnover = fresh). Verify that the stems are crisp, juicy, and substantial for their size. Engage in polite haggling and ask locals "freshest today?" They ripen quickly in hot climates, so wash or peel them after you buy them. Around the world, tasty, affordable market hauls are made possible by long lines and clean carts.
