Since 1988, SSSIO volunteers in the greater San Diego area in California have offered freshly-cooked food to the homeless every Sunday. In the beginning, volunteers prepared bean burritos and peanut butter and jelly sandwiches and distributed them along with water, fruits, and pastries to the homeless.

In recent years, the volunteers served a buffet-style meal every Sunday afternoon. Around 120-200 homeless persons would line-up to receive a hot rice-vegetable dish and their choice of several hot dishes, salads, and fresh fruits. The service activity was further expanded to distribute clothing, blankets, hygiene kits and school supplies. Additionally, food and clothing were distributed at an orphanage in Tijuana, Mexico which is near San Diego.

When the unprecedented Covid-19 pandemic hit in March 2020, SSSIO volunteers distributed sandwiches, fruit, and water, along with packets of rice and pasta, while following safety protocols. The volunteers supplied face masks and sanitizers to the homeless as a preventive measure during the pandemic. They also gave away hats during the summer heat wave and beach mats for sleeping on concrete floors.
