Multi-Layer Dip

I just made this dip for a birthday party at work, and everyone RAVED about it! So I wanted to share it!

You can make this many ways, and many times it is called a 7-layer dip, but for some reason mine is only about 6...add and subtract as you please!

1 can refried beans (if you use vegetarian, they taste as good and aren't made with lard!...a little bit healthier!)
1 packet taco seasoning mix
8 oz. sour cream
1 8 oz. packet of Ranch Dressing dip mix
Aunt Cindy's guacamole (recipe below)
1 large tomato
Red onion to taste
Garlic powder
Fresh ground pepper
Kosher salt
1 regular bag of shredded cheese (I like Mexican 4 cheese)
shredded lettuce (enough to cover the whole dip)

1. Mix the refried beans and the taco seasoning mix; spread over bottom of a large, shallow casserole dish (9X11, I think?)
2. Mix the sour cream and the ranch mix; spread over the refried beans
3. Make the guacamole; spread over the sour cream
4. Cut up the tomato and some red onion, mix with garlic powder, salt, and pepper; spread over the guacamole
5. Spread the cheese over the dip
6. Top with the shredded lettuce!

You're done and it is delicious! Eat with Tostitos!

*Note: I thought it was a little bit salty when I made it, but I think I put too much of my own salt into it...the ranch and the taco mix are salty by themselves, so I would add any more sparingly.

Auntie's Guacamole (this is my rendition of it for this dip...if you're making this by itself, it is mostly the same, you would just probably make more!)
-for this dip, I used 2 avocados...you can use more!
Mash avocados, put in 1 or 2 teaspoons of mayo, a squeeze of lemon juice, and a couple shakes of the following: ground pepper, garlic powder, kosher salt
