The only way your going to find TexMex in New Jersey is if you make it yourself...which actually...isn't too hard if you like cooking. I'm one of those guys who can taste most ingredients in foods when I taste them and it wasn't too hard to replicate some of my favorite dishes.
One good quick meal I made...
Ingrediants"
Flour tortilla's
your favorite cooking oil
re-fried beans
Velveeta cheese
Rotel Diced tomatoes
Avacado
Onions
Bell Peppers
tomatoes
garlic powder
onion powder
salt and pepper
Beef or chicken fajita meat (pre-seasoned is fine)
Take the avocado's smash them in a bowl with a fork
add onion powder, garlic powder, salt and pepper
add diced tomatoes and a small amount of diced onions
stir and put in refrigerator
Take a half block of diced velveeta cheese and place in a pot
Take a can of rotel tomatoes and pour in pot over the cheese
(You can drain the juice for a thicker cheese dip but I don't because it hardens quicker..I personally pour the juice in as well...by the time it cools down a little it is perfect)
Put on medium-high heat and stir till all the cheese is melted
(Make sure you don't let it burn the bottom and stick to the pot)
Once done, turn off heat and stir every now and then
Cook your fajita meat on the grill with sliced onions and bell peppers and it have on a plate ready to go.
(I begin this step while the fajita meat is cooking to take up the in between time)
Take flour tortilla's and cut them in half, then half, then half again..making a lot of little triangles.
Pour a thin layer of cooking oil in a pan and heat around med heat
when it reaches desired temperature....start adding in the flour triangles
(Don't pour them all in...lay them flat and even so they all cook on one side)
You'll have to get your own timing down and flip them all over (I cooked on by itself to time it)
(Starting In the same order you put them in because seconds count with these little things)
After you've cooked both sides to a golden crisp, take the tortilla chips out and place on a plate with a napkin on it. (Help soak out some of the grease)
Warm up the can of re-fried beans
Next, I take cooking shears and chop up some of the fajita in to inch long pieces
Spoon out some beans and place a little on each chip
Next, Put on a few pieces of diced fajita
Pour over the cheese dip
and a spoon of guacamole and BAM..I swear to you..the best Fajita Nacho's you've ever taste.
I always end up using the other half of the fajita to make actual fajitas as well.
Its not the entire Tex-Mex menu but I promise it will remind you of home that night....It did for me
Enjoy!
