Eating food without offering it to Krishna
I am living in US and I'm a new devotee. With a non-vegetarian family and no altar or prayer room in my house, I couldn't prepare food for the Lord eventhough I prepare pure vegetarian food without onion and garlic. Every time I eat, I feel so bad and guilty because I'm eating food without offering to Krishna. Is there anything I can do before eating without serving the Lord? Is there any other way like reciting a mantra or something?
I need help. Please reply ASAP.
