Another recipe I saw used chopped avacado instead of guacamole, so this would work better with your avocado.

I just made this:

16 oz fat free refried beans
3 avocados (mashed)
1 tsp lemon juice
1/4 tsp salt
1 cup sour cream
2 tbsp fajita seasoning
1/2 cup shredded mexican cheese
sliced olives
scallions
tomato

Mix smashed avocado w/ lemon and salt. Spread beans on the bottom of 9 x 13 (i used 8 x 11) glass pan or medium size bowl. Spread avocado over that and then sour cream. Sprinkle fajita seasoning on sour cream. Then top w/ cheese, olives, scallions and tomatoes.

Enjoy!
