Hi! I live in lake forest
Mothers market is in Laguna hills, not far away, and they have a restaurant that serves breakfast
Non breakfast: many places actually. Here are some non-chains you might not know have vegan options.
Luna Grill, get the falafel wrap, no cheese, in the wrap, no tahini sauce, sub hummus. Great falafel
Veggos is a raw, vegan spot
Lees sandwich is Vietnamese sandwiches. Get the vegetarian, no mayo, sub avacado
Urban grill in foothill ranch (very close by) has vegan options, knowledgable staff
Baja fish tacos, get the veggie bowl, black beans, no cheese. Really really good.
Mesa grill (right in the border of mission viejo) has vegan options. Just say vegan, they will know.
And many, many more in close by cities, maybe 10 minuets away. Veggie frill, native foods etc. Let me know if you have questions!
