Dinner

Go up to a street person and offer to buy them dinner. You’ll be buying Jesus a meal. "In as much as you have done it to the least of my brothers or sisters, it’s as if you have done it for me." Jesus said, in reference to good works done for others.

If you sense it is safe to do so, actually take them somewhere and eat with them and be good company for them. If you are unsure that would be wise, simply give them money for a meal, or ask them if they would like you to buy them something to eat and if so take their order and return with the meal.
