This is how I did it with all three of my kids:
Cereal at lunch, until s/he was up to a 1/4 a day. Then veggies at lunch w/cereal, cereal at dinner. I started with the green veggies first - I started with the less sweet stuff first. When I went through the green veggies, I started with the orange, and then s/he was eating a yellow veggie at lunch and a green at dinner, all mixed with 1/4 cup cereal. Finally I added fruit at breakfast, starting with prunes, mixed with cereal, so that they were eating a fruit at breakfast, and veggies at lunch and dinner. At 6 months, I started adding meats, at lunch. Now, my boys were both huge eaters, so at dinner I also was giving a fruit at dinner for dessert. With my 7 month old I give him yogurt at lunch. This is a typical day for him
Wake up, nurse.
Breakfast - Stage 2 fruit with 1/4 cup cereal
Nurse and nap
Lunch - Stage 2 veggies w/1/4 cup cereal, Yobaby yogurt, usually some sort of gerber puff or cheerios while he's waiting.
Nurse and nap
Nurse after he wakes up depending on how long until dinner
Dinner - Stage 2 dinner(with meat) mixed with cereal(my kids all liked thicker consistencies), stage 2 dessert mixed with cereal. Again, he will have something to tide him over sitting in the highchair while I get dinner on the table for everyone.
Nurse and bed.
Good luck!
