Anything with coffee is breakfast. What is your objective, to make veggie options available for any veg*ns there, or to make accidentally veggie food that everyone likes? If it's the first thing, you could make some kind of veggie burritos with beans, rice, your favorite vegetables, and salsa. Or a stove-top sautéed vegetable scramble with tomatoes, onions, peppers, mushrooms, spinach and potatoes. If it's the second, maybe you could make hash browns or home fries.
If you have (or can borrow, or the church has) a waffle iron, you could set up a waffle station with batter and sliced fruit, besides spread and syrup.
